You know, it actually occurred to me to use a DVD instead of a CD at some point, but by then I was determined to get an export working in code. I'm glad I chose the code route now, because I have all my photos from two MacBooks on a single drive and I can work on merging the libraries.

I might need to write a merge too, but I think I can use one I wrote in Scheme a while back. I use it to back up iTunes now, and it works great. iTunes is easier than iPhoto, because the files are more visible: but now that Perl's got the images exporting, standard tools ought to make the rest of the chores easier.
