The dreaded red X

I know this subject has been covered over and over but I've personally never encountered much of it so I haven't ever looked into it. I load some photos into a well used realm, post them on my forum. I can see the pics, some members can also but a few cannot. Is the problem on their end or on this end? Thanks.
