Excluding folders from the gallery

[NevadaXJ]

So I have a Droid running 2.2, although I would imagine this would be for 2.1 as well.

I have some pics on my phone... that..um... would be bad if some people saw them. I put them in a special folder on my SD card, but like an annoying puppy, my Droid dug them up and plastered them into the gallery.

Is there any way to exclude folders from the gallery? Ideally it would be like having pictures only in the pictures folder show up, and no others. I just want to use Astro to get to them, and not have to worry about someone checking out my phone accidentally stumbling upon these pics...
