Can't comment on the "pixel" discussion.

Right - the UA-based limitation of file size, mime type and file count
are undoubted important improvements. Being able to restrict the picture
dimension before the file is getting send to the server would be nice.
We might someday get an OS/UA that is able to only list the pictures in
the valid size to select - or provide an "automatic resize to fit upload
guideline" function . (I?m using Java applets today - would be nice to
get ride of them in the WF2 generation browsers).

Example tag... (just an idea)

<input type="file" name="avatar" accept="image/*" maxlength="81920"
dimension="256,256,32,32" />

Keep the byte.
