 The Image::Size module on the CPAN should help you.

Thank you for your reply. Yes, it worked -- although I had to tweak somehow the source: replace the end of lines with cr, comment out the lines "use AutoLaoder" and "__END__".

Now, I would like to ask you how I can trap error when I invoke a module, but that module is not installed on the user's environment. Perhaps should I use "eval" -- but how...?

Thank you in advance for your help!

After re-reading your message, I have noticed that you had to "tweak somehow the source". Huh? Looks as if you have installed the module by hand. Please don't do that until you really know what you are doing. I recommend to use the installme.plx droplet, that comes with your MacPerl distribution. Simply drop the packed or unpacked module on this droplet, and answer the upcoming question "Convert all text and MacBinary files?" with "Yes". This should install the module properly.

Regards,
Thomas.
