--- Comment #6 from Jeremy Newman jnewman@codeweavers.com --- I wrote a patch for the AppDB that loads the images from our CDN. The original image is used now and not dynamically resized on the fly.

Note, images may still get resized to a maximum size on upload. I still need to look into that. Might be better to just block images over a certain filesize then resizing them.
