>I have the following list of image files .
When searching the latest (numbered file) in this particular case its
background_4.*** and its a .jpg file - but - the latest file in the list
could also be a .gif file at times .
zimages_background/background_1.jpg
zimages_background/background_2.jpg
zimages_background/background_3.gif
zimages_background/background_4.jpg
etc etc
How do i do a wildcard file extention search to find the latest numbered
image - regardless if its a .jpg or .gif .
I know how to search for the _* number in the filename & its how to do a
file extention wildcard search i need .

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.
