uploads: fix stretched images on Safari.

Browse Source 
Fix images on the upload page appearing stretched (having the incorrect aspect ratio) when the image
is enlarged on Safari.

The fix is to set `aspect-ratio` and `height: intrinsic` to ensure the image is the right size. I
have no idea how this works or why it's necessary on Safari.
