You might be one of the few that does this. I get MANY complaints of slow mobile image downloads.L
I make it policy that I upload and link 1200 pixel wide images for in-line viewing, and if a larger representation is needed that is made available by an explicit additional link so that viewers know they will be downloading something big. That way my flickr original upload is always the correct size (typically 125-400K) and renders properly on all devices without too much unnecessary overhead.

If these continue or intensify, then I will be essentially forced to reinstate the "new" way of image management.
