How do I attach pics on FSOT?? (I'm very tech.challenged...)

[Gabrielsmama]

OK...so I want to sell a lot of my cloth diapers I don't need anymore but I don't know how to post pics in the FSOT!. I'm really technologically challenged and would appreciate instructions like you gave them to a 5-year old...lol. I created a Photobucket account but it seems finicky (not sure if it's the site or my laptop). I didn't figure out how to get the pic from there to the thread itself.

I'd hate to hoard on the diapers just since I can't sell them due to this stupid problem...

Thanks in advance!
