Are you saying that you think there's something about that image (lace.png) which is causing it not to be attached?
Is that the original file that the other member attached? Or is it one that you fixed for her/him, so help solve their problem?
Clearly there's a problem with the forum, so it probably would be a waste of time to try and troubleshoot that image file.
I've downloaded it, so I'll try and attach, so I can see what the problem is.
Oh I see. 3600 x 3600 pixels I think I've uploaded attachments as large as 3900 or more, but I'd have to search to find out. It could be mine were very long but not that wide. But that could be close to some limit. Let's see what happens....
Edit
Yeah, it wouldn't attach for me either. I'll investigate about the size issue. However, trying to attach it didn't seem to affect this topic like in that other topic. I'm guessing the attachment issue is a separate problem.
