image loader for `file://` is blocking, while image loader for `http://` runs fine. #5375

Describe the bug When using

ui.image("file://image.png");

it is blocking until the image is loaded.

But

ui.image("https://web.site.com/image.png");

will run fine and updates the GUI while the image is loading.

Expected behavior All loaders should be non-blocking.

Desktop (please complete the following information):

OS: macOS 14.6.1
Version: egui 0.29

This should definitely be improved, I think it would be fine to just spawn a thread to load and decode the image? Seems like someone already opened a PR: https://github.com/emilk/egui/pull/4069 But it's stale and needs some more work before it's ready.
