A lot of members had their sigs in the old galleries and were linking to them...
Well you can still do that - just change the url of the image in your sig to include the "archive" directory:
for example
http://www.latelatecrew.com/forums/uploads/1171820999/gallery_173_3_5506...
becomes
www.latelatecrew.com/forums/archive/uploads/1171820999/gallery_173_3_550...
You can find the old forum galleries here: http://www.latelatecrew.com/archive/forums/index.php?act=module&module=g...
You will have to be logged in to the old website to see them.
