Whoa. My post from last night is not here!!!
Thanks for the reply, Mike. I missed it yesterday until evening (see above). When you say "size" do you mean file size, or actually shrinking the image, thus making the file smaller as well?
I have no familiarity with iPhoto. I don't know if it came with the OS. I don't know what level of OSX he has. The iBook he has was purchased in the summer of 2004.
I have used a digital camera at work, but do not own one. I already asked my son in an e-mail if he has iPhoto, and what OS he has. It may be a few days before I get an answer, but he is being very diligent about answering all of our questions when he does respond.
