Can't get photobucket to work w/ my new Mac

[Howard Beale]

First off I'm MUCH older than the rest of you and am a tech dummy so plz don't laugh too much. Anyway, I'm posting this from my (brag) brand new 24" iMac. Prob: When I go to photobucket now and hit browse it doesn't bring up my albums in iPhoto to select a picture from like it used to on my old iMac. Can anybody tell me what I'm doing wrong or do I have to call support? The only thing I can figure is that I've got something set wrong or somesuch but I don't know how to fix it.

Tx for any help.
