Multiple images from stim lists

[jarvis24]

Try revising such that the stimlists don't use the .bmp extensions like this:

pic1
pic2

I've attached sample to show you. It may be a bug having to do with the explicit use of ".bmp". If you leave it off in the stimlist, DirectRT assumes it's an image file so that's probably the easiest solution for now. See if it helps.
