Re: More RegExp help...

[Scott Stroz]

Good point...then I might consider this

ListFirst(ListFirst(fileName,"."),"_")

Again, this is assuming teh format of th efile name will not change..

Except he also needs to remove the "_640x640" part.  However, you could 
do the same thing with underscores instead of periods.

And if the filename COULD contain other periods:
listDeleteAt(filename,listLen(filename,"."),".")

which says, delete the last list item using "." as list delimiter

Re: More RegExp help...

[Scott Stroz]

I love RegEx, and use them frequently. However, they are not always my first 
choice. I would actaully use:

ListFirst(fileName,".")

Assuming there are no periods in the file name. 

This may actually be a bit quicker since you don't use the Reg Ex engine.

If the pixel size (I assume that's what the numbers are) is always a 
square, you might use backreferencing to make it a bit pickier, but it 
probably isn't necessary.

Assume the usual caveats.
