I'm trying to attach an image to a message. When I open the "media to show" box, it has a list of all of my images, but the image I want will not attach. The box just resets to "none." I tried the other images listed, and only about 1/3 of them were accepted for attachment. The ones that were accepted were of various types (i.e. jpeg, gif, png, etc. and of widely varying dimensions and size. All those rejected were jpegs and those were also of various sizes (91x91 to 180X287). All the images had been previously attached to other things like zones, items, characters, etc., if that makes any difference. What's going on?
