aww maaaan you mean I have to make them all attachments? I will second the comment about not being able to have written descriptions for each one. A lot of my earlier images are freakin huge, and that presents a problem when viwing with attachments.
I dunno but I keep a careful inventory of my art on my site, and I rarely move my stuff around. so If I link to an image off of my site, chances are, it wont move. but eh. i understand the need to archive, specially for the pro work around here. that way if someones site is down, their art wont be.. but if the actual forum is down, it wont matter.
for finding your sketchbook: do a search and type in the exact title. for me, i just type in 'kina's sketchbook' in search, and there it is! quick and easy. just.. dont forget what your post is called
