Thank you, I couldn't answer right away. Low Blood Sugar.
You can also post directly from a photohosting site. I use photobucket.
I just go to the reply box and click on this icon
Then I paste in the direct image link that I copied from Photobucket into the space in the drop down box that appears.
You must be sure you take out the auto-populated http: or you will get two and your photo will not appear. This method of posting will allow you to add text above, below, or beneath your photos.
I don't use the forum's Gallery because you cannot delete any of your photos from the Gallery. You can only replace them.
