Ah, I see. This is not a single album limit, but instead is a limit of 100 photos across all albums you have. Bummer...guess I'm down to zero.
I deleted a little album I didn't need and got 5 photo slots back. But then I used them up for the album I was just creating.
I found this feature worked real well for including photos inline with bb code vs adding as attachments at the end of a post. But this means if I delete albums I'll trash prior posts with broken links, so I'd better not do that.
