Once you have uploaded your photos to the gallery, select the largest version, click on your right mouse button, and select "properties." A box will open that shows a file name like this: http://gallery.photographyreview.com...637katyn_1.jpg
Drag you mouse over this text and press the Ctrl and C keys to copy the link. When you type up you post, type <*img src=" and then press Ctrl V to paste in your link. Close the string with "> and your image will appear along with your text when you post. Ignore that asterisk, though, I had to put it there to keep the program from thinking I'm posting an image and to show the tag.
