Apple

set these_files to every file of folder this_folder whose type identifier is in {"public.tiff", "public.jpeg"}

but only

set these_files to every file of folder this_folder whose type identifier is "public.tiff"

I don't know if this helps, but

set this_folder to (choose folder)

tell application "Finder"

set these_files to every file of folder this_folder whose kind is in {"JPEG-Bild", "TIFF-Bild"}

end tell

works.

Cheers

Thomas
