Well....that example should have been
(ex. somefilename.tiff would now be KeyID.tiff)
See here how to export images from container fields.
For renaming the files, you will need to get the original file's extension - this will normally be:
Let ( [
path = GetAsText ( YourContainerField ) ;
len = Length ( path ) ;
pos = Position ( path ; "." ; len ; - 1 )
Right ( path ; len - pos + 1 )
Thank you kindly....apparently there was a forest in front of that tree....I just needed to concat the file extension onto my export script's variable filepath....
Have a good one!!!
