Summary:
I've seen quite a few newbs trip on this, so I'm fixing it.
First - you have to set the width/height on a remote image, otherwise nothing shows. This is [even on stack overflow](http://stackoverflow.com/questions/30091398/unable-to-display-image-with-react-native-with-uri).
Second - with the addition of ATS in iOS most people who copy/paste this example will not be able to load an insecure image, so I changed it to the `https`.
**RESULT** this doc becomes copy/paste friendly again for beginners.

Summary:
Before this PR, ```RCTImageLodaer```'s Cache was too big(200MB on disk) and It doesn't work with HTTP Cache-Control header. So to provide dynamic image, the users must have to add random value on url( ex. adding current date) to avoid cache.
So I change that cache system to default ```NSURLRequest```'s cache system, which is well-working with HTTP specs. As the discussion on this issue #7571 , making custom cache policy processor is not ready yet and useless, over-tech things, I think.
Even we have no plan about image cache system(or would change plan later), before having a nice plan, I think we should let user use image module with common HTTP Specs.
So I remove custom ```NSURLCache```, and make logic like below,
1. try fetch image,
2. on response, get ```Date``` on response's header and make ```cacheKey``` with ```Date```.

Summary:
This uses `[UIImage imageNamed:]` to load local assets that are bundled using `require('../image/path.png')` and makes sure it is done synchronously on the main queue to prevent images from flickering. This improves user experience a lot when using large local images and prevents icon flickers to match the behaviour of most native apps.
This adds to methods to the ImageLoader protocol, one to tell if the image loader must be executed on the url cache queue and one to tell if the result of the image loader should be cached. I then use these to make the LocalImageLoader bypass the url cache queue and avoid caching images twice.
Note that this doesn't affect debug builds since images are loaded from the packager.
I'm not sure if we want to still support async loading of local images as I'm not sure how much of a perf difference this will make. Maybe someone at fb can benchmark this see how it affects your apps but there wasn't a noticeable one in mine. Also I only enabled this for loading png and jpg im

Addresses this comment: https://github.com/facebook/react-native/issues/2296#issuecomment-232446493
This pull request adds the `center` value to `ImageResizeMode`.
When set, it will center the image within its frame.
If the image is larger than its frame, the image is downscaled while maintaining its aspect ratio.
That is how the Android implementation works, too.
Sorry, don't have time to write tests. 😢
Any reviewers should make sure `RCTTargetRect` returns the correct value when:
- the image is smaller than its frame (ie: no downscaling needed)
- the image is larger than its frame (should be downscaled to avoid clipping)

Summary:
Hi there,
Here is a fix for #7538 (and #5085).
I had originally discovered this issue when using `resizeMode` through the style props. Although this might arguably be an incorrect usage (see https://github.com/facebook/react-native/issues/4759#issuecomment-164301166) the same issue would happen with the `tintColor` and `overlayColor` style props.
To test this, you can render the following:
```jsx
const imageContainerStyle = {width: 100, height: 100, backgroundColor: 'green', marginLeft: 10, marginTop: 10, };
const imageStyle = {flex: 1, width: undefined, height: undefined, resizeMode: 'contain', };
return (
<View style={styles.container}>
<View style={imageContainerStyle}>
<Image style={imageStyle} source={

Summary:
This adds a new resize mode for iOS 'repeat' that tiles the image over it's frame. This allow to easily create a view with a repeating background pattern which there is no way to do at the moment without including a bunch of different sized assets.
I'm not 100% sure it should be a resizeMode or a separate prop but I went with resizeMode since it made more sense to me and the are not really any use cases where we'd want to use this with another resizeMode other than 'stretch'.
**Test plan**
Tested mainly by adding a UIExplorer example, also tested that changing the resizeMode prop from and to 'repeat' worked properly.
I'd like to implement this on Android too but it is a bit trickier since Fresco's ImageView doesn't support image tiling and would require submitting a PR there too :(

Summary:
This adds support for specifying multiple sources for an image component, so that native can choose the best one based on the flexbox-computed size of the image.
The API is as follows: the image component receives in the `source` prop an array of objects of the type `{uri, width, height}`. On the native side, the native component will wait for the layout pass to receive the width and height of the image, and then parse the array to find the best fitting one. For now, this does not support local resources, but it will be added soon.
To see how this works and play with it, there's an example called `MultipleSourcesExample` under `ImageExample` In UIExplorer.

Summary:
Under rare and as-yet-to-be determined circumstances, images can sometimes fail to load/download and get "stuck", without producing an error.
Because the `RCTNetworkTask` for these images is stuck in the "in progress" state, they clog up the RCTImageLoader task queue, which has a limit of 4 concurrent in-progress tasks.
This was previously masked by the fact that we automatically cancelled image requests when the RCTImageView moved offscreen, but we no longer do that.
This diff adds logic to detect some types of stuck task and remove them, thereby unblocking the queue. I've also restored the functionality of cancelling downloads for offscreen images (but not unloading the image itself) so that stuck images will be cancelled when you move to another screen, instead of using up space in the queue forever.

Summary:
As per https://twitter.com/olebegemann/status/738656134731599872, our use of "main thread" to mean "main queue" seems to be unsafe.
This diff replaces the `NSThread.isMainQueue` checks with dispatch_get_specific(), which is the recommended approach.
I've also replaced all use of "MainThread" terminology with "MainQueue", and taken the opportunity to deprecate the "sync" param of `RCTExecuteOnMainThread()`, which, while we do still use it in a few places, is incredibly unsafe and shouldn't be encouraged.

Summary:
Allows developers to specify headers to include in the HTTP request
when fetching a remote image. For example, one might leverage this
when fetching an image from an endpoint that requires authentication:
```
<Image
style={styles.logo}
source={{
uri: 'http://facebook.github.io/react/img/logo_og.png',
headers: {
Authorization: 'someAuthToken'
}
}}
/>
```
Note that the header values must be strings.
Works on iOS and Android.
**Test plan (required)**
- Ran a small example like the one above on iOS and Android and ensured the headers were sent to the server.
- Ran a small example to ensure that \<Image\> components without headers still work.
- Currently using this code in our app.

Summary:
Previously, only Text and Image could be nested within Text. Now, any
view can be nested within Text. One restriction of this feature is
that developers must give inline views a width and a height via
the style prop.
Previously, inline Images were supported by using iOS's built-in support
for rendering images with an NSAttributedString via NSTextAttachment.
However, NSAttributedString doesn't support rendering arbitrary views.
This change adds support for nesting views within Text by creating one
NSTextAttachment per inline view. The NSTextAttachments act as placeholders.
They are set to be the size of the corresponding view. After the text is
laid out, we query the text system to find out where it has positioned each
NSTextAttachment. We then position the views to be at those locations.

Summary:
Some apps are complaining about flashing images when performing navigation transitions. An example issue would be:
1. Load a master list view with many images
2. Click on an image to go to a detail view
3. Go back to the master list view
At step (3), users see a number of images flash from a placeholder image back to the final image because `-[RCTImageView didMoveToWindow]` calls `clearImage` when the image view exits the view hierarchy between (1) and (2) and calls `reloadImage` (which sets the image property asynchronously) when the image view re-enters the view hiearchy between (2) and (3).
This diff fixes the issue by being less aggressive about clearing image contents. It only clears image contents when the app receives a memory warning or the app goes into the background.
For comparison, CKNetworkImageComponent in ComponentKit doesn't have this purging behavior at all.

Summary:
In RN we cache image data after loading/downloading an image, however the data we store is the compressed image data, and we decode this asynchronously each time it is displayed.
This can lead to a slight flicker when reloading image components because the decoded image is discarded and then re-decoded.
This diff adds a small (5MB) cache for decoded images so that images that are currently on screen shouldn't flicker any more if the component is reloaded.

Summary:
This works with D3305161 to minimize image flashing. After D3305161, the completion handler passed to `-[RCTImageLoader loadImageWithoutClipping:size:scale:resizeMode:progressBlock:completionBlock:]` may be called back on the main queue in the case of a cached image. In this case, we want to set the image view's image property synchronously rather than on the next runloop iteration via dispatch_async. This minimizes the amount of image flashing the user sees when displaying a cached image.
The exception to this case is for blurred images. A blur can be an expensive (taking multiple ms on the CPU), so we always make sure to perform the blur off the main queue even if the image is cached and the callback came back on the main queue.
