Motorola RAZR V3i / V3t / V3e / V3r

Hi, is there a way to arrange the photos on my memory card so that they are listed in a certain order when I browse through them in the "pictures" menu? I don't want to put things into separate categories. I just want the less-embarrassing ones to show up first when my friends grab my phone and start browsing through the pictures 😉

I think the phone sorts them in the "All" category automatically by date/time taken. Even if I could just find a way to put them in alphabetical order that'd be fine, because I can then re-name them myself!

Thanks!
