Thanks. Do you want to have the image in the center and text either side or just an image in the center? To get an image centered you can use <center> (and </center>) like I do below. To get text either side of it is going to be a bit more of a challenge (and would probably look a bit funny).
Yeah, I actually tried this on my latest post and it did look weird. I pull-right the Source hyperlink of a big image, but anything smaller that I center I have to put the Source hyperlink directly below it or else it looks super crazy.
div treats creates a new block that I think can make things a bit awkward. I would imagine someone with more html skill than me would have other ways of doing it.
