It's difficult for us mods to monitor each and every post for blown-up images since we simply can't open each and every pic and see at 100%. By far upscaled images are the most difficult to spot and we definitely appreciate any help we can get from our fellow members.
UC, I know it's simply too much to ask you to report each time you come across such a post, but if you can try and bookmark/copy the post links and PM the bunch of them to one of us mods, we can take care of them. Same goes for all our members, if you see a bunch of posts that are problematic and don't want to report them one-by-one...then copy the post link and PM us.
FYI, each post's subject line is hyperlinked with it's own unique link.
For example, the link of this post is : http://forum.usemycomputer.com/index.php?topic=36558.msg87253#msg87253
