elaine, if you use the "bulk upload" (it's a small hyperlink) it will grab
all the photos on your DESKTOP.
I usually use that method, selecting ALL then deselecting any I don't want. It seems to go really fast.
When Photobucket has uploaded all of them, each photo will have the options below on what to do with them. I typically use the HTML option and paste that text inside this MESSAGE area.
If you want to run a slideshow, make yourself a separate album. That way those specific photos will be all in one spot.
