Sometimes I have that problem too
I have no idea why but sometimes when I click on the "manage attachments" button nothing happens, same thing with the smilies. I have had luck using a different browser. I have Netscape, IE, and Mozilla firefox. Can't remember now which one actually works. I guess it has something to do with the settings..but I never change them so don't know what's up. Sorry
Wish I could help more cause I'd really love to see your pictures!
