Rannie pointed me to this link that shows a way to have more than one photo in one entry using php. I haven't tried it myself – but it looks pretty cool. (You can see how Rannie used that code here (click on the little boxes below that photo).
Also, if you're into photoblogs, you probably noticed that it wasn't a category in this year's bloggies – so "if you're not invited to the party – best thing to do is have your own!" LOL! Here's a contest just for photoblogs! (run by Rannie)
