Blog Questions For You

Okay all you blogging geniuses out there-I've got a friend who would like to know how to make a photo slide show and post it on her blog. Anyone know how?
And on that same note, anyone know why my layout keeps disappearing? I did it the same way as my Kellerspace layout and that one is still there. Very curious.
Anyone else have any blog questions? I know there are some of you out there with questions and some of you with the answers!
