Anyone?
Here’s one thread on it: http://forum.slowtwitch.com/gforum.cgi?post=1384720;search_string=how%20post%20picture;#1384720. There are lots of others if you do a search. When you have an uploaded picture on one of the hosting sites, you just click on the image icon (far right) and past the link – delete the http:// first. Also, you may want to resize your image before posting.
