Yes, thanks Joan. I think the instructions Gayle gave are a little dated at this point, so here are more detailed instructions that will work now:
The best way in Photobucket is, once you're in your Library (or an Album, which is just a further subdivision) click on the pic you want to share to open it on its own page.
Then look to the right for "Share this Photo" and the four choices below it.
For this board you need to use the HTML URL form, the 3rd one down that begins with a < .
You simply click on the box and it should turn yellow and briefly say "copied." Then come back here and paste your copied URL in your post, ie. right click where you want it to go and choose Paste from the menu that appears.
A long, long string of gobbledygook info appears which will turn into a photo once you finish your message and hit Post, or Preview to check that it worked correctly.

I hope that helps, Judy. Looks like you got at least one pic to work.
