Good one! I'll have to think a bit on that pic.
To get a photo off the net:
-Find the pic you want
-Right click and go down to "properties"
-highlight the address portion (usually ends with JPG or similar on photo)
-right click and go down to "copy"
-go back to Scubaboard
-in the Quick Reply box, click on the little square thing that looks like it's got a mountain in it (it's the "insert image" icon)
-paste the info you got off the photo and hit "okay"
That's it!
Seems like a lot, but after you do it a couple times, it's a piece of cake. If I can do it, anyone can.
