... you may have to learn how to swim in the guinness... here you have the script to find out the width and the height of every picture in a .sla file: === 8< === #!/usr/bin/python import re file = "" width = 0 height = 0 pf = re.compile('PFILE="([^"]+)') pw = re.compile('WIDTH="([^"]+)') ph = re.compile('HEIGHT="([^"]+)') f=open('/home/ale/test.sla', 'r') for line in f: if 'PTYPE="2"' in line : m = pf.search(line) if m : file = m.group(1) width = pw.search(line).group(1) height = ph.search(line).group(1) print file, width, height === 8< === it's doable... but since you're scared by the python, i guess it's better not to give you the last part: resize the images with PIL or imagemagik: i don't want to be held responsible for some deletion of files on your system! good night! a.l.e
