It was on MARS... of course!!!
I tend to do a lot "manually".
Look at the top of the page, just under "BIKE FORUMS", and you'll see "Gallery". Now, that brings up a bunch of pictures, but to the right, you'll see "My Pictures".
Now, that gives you all the albums (you can create more than one if you wish).
Keep clicking on the album/photos until you see your picture. When it gets as big as it will get, right click on it and choose "copy image link".
Then go into your message and insert
[img
]Your Image Link
[/img
]. You may get that by clicking on the upload picture button

, but then you may get to copies of the photo.

...
Did you use the upload picture button:

, or did you use the attachment button:

?
As far as picking up someone else's album. There has to be an easy way... I think. But I just find the user's user number and change the address to point to that.
