Is it possible to swap images before a scene / project loads?
I need to update an old educational project (not Saola) that is normally run on classroom desktops but will now include some iPads on Wifi and was wondering if I could give the user access to high resolution images for their retina screens as the project is only 1024 so the images are currently also 1024 and tend to be blurry.
I know I could simply use 2048 x 1536 images for everyone but I also know that some school have classrooms away from the main hotspot points and the Wifi can be weaker making it impractical to load larger file sizes.
I thought about using scrset with an x-descriptor but I wasn’t sure if the browser selects the image based on just pixel ratio or connection speed as well? Also it would mean having to put all the images inside HTML Widgets which I’d rather not do.
Therefore if I give the use the choice, can Saola change the scr of an image before it loads?
