 * Creates a helper function that can be given a src string "needle" to find in the "haystack" {@link AssetMatch.matches} and returns its associated {@link AssetMatch.sourceImage}. If no match found, the helper function returns the sourceImage of the first item, just to ensure a valid image is returned.
