I'm sure this is a stupid question, but as they say, "the only stupid question is the one you don't ask", so here goes...

How do you post photos so that the hi-res version appears on screen? I am able to post links to photos stored on my ISP, and I know how to post the low res thumbnails, but I can't find anything in the help file or elsewhere to getting the photos to appear within my post automatically.

Please help.
