hope i'm not one of them...not sure of my association with the lapdogs. if
you mean republican, i tend to go that way on fiscal and domestic policy,
however r's look more d than d's do these days. if you only mean mentally
entrenched to blindly follow...i can assure you i'm not. ;^)

here's a flexible function to list files and one to return the file number,
followed by an example with your data above. if the image doesn't meet
image_number.ext, then the whole file name is returned and the version
number will be zero.

hth,
