Please list step by step if possible.. I am proud of my acheivement and would like to see it in my signature, but haven't figured out how to do this yet!
ETA: These instructions also work when inserting images in a post.
If you have a Fotki account, you may have a button labeled "Share Photo" or something like that. Click it and it should give you the picture URL. If the Fotki URL doesn't have the IMG tags, just click this button
in the reply box and paste the URL in the text box that opens.
