`RemoteImage` now uses two images: a high res image (as before), and a new low res image which will be used if it is available before the high res image has been loaded. To enable this, it now uses two `ImageLoader` instances, one for to fetch the low res image, a second for high res image. It assumes that the low res image url is the same as the high res image url, with a suffix appended (default `_low_res`) to the file name, eg `/images/myImage.jpg` is assumed to have a low res equivalent at `/images/myImage_low_res.jpg`. It requests the high and low res images concurrently, and displays an error when both requests fail. A low res image will never replace a high res image even if it is received last. Here is a video of it loading a "low res" image, following by high res image. For this video the low-res image was intentionally set to a completely different image to make the change easy to see. If you move the slider manually you can control the speed. https://github.com/RevenueCat/purchases-ios/assets/109382862/97521803-5c12-43d0-92a8-596b23cdcff6 --------- Co-authored-by: Josh Holtz <me@joshholtz.com>
