Fancy Blogging Questions

For all you Blogger experts out there . . . .

I've been using the "Hello" program to upload and post photos on this here blogspot blog. How do I post 2 photos in the same post? And what if I want text both over and below the photo- how do I do that?

And, how can I tell blogger to put a picture in the right-hand column, rather than in a post? I mean, I know the HTML code for that (sort of), but wouldn't know how to upload the photo in a way that blogger knows that the picture isn't for a posting.

help!
