Hey Rachel, are your pictures on imagestation? If so, its actually very easy to post your pics, like anything else it's only easy when you know how!
If you use imagestation; go to your album and select the picture you want to post, if more than one pic is to be posted, I just open my browser again so I can go back and forth between here and there. Once the pic is selected, right click and look all the way down to properties and select that. A window will open;look for Address and under that (URL) Highlight ALL of that info to the right (make sure the last 3 letters are jpg) and copy. Come over to PT and start a new thread. Click IMG and a new box will open. Now, paste and click ok. Voila!!
Hope this helps!
