Migrating over 2,500 photos from Gallery2 to Flickr

I've been in the process of migrating my parents photos off a Gallery2 installation on to Flickr.
Not normally a big task, but when it contains over 2,500 photos, some 120+ photo sets and over 1GB in image data.. it's no mean feat!

Searching online it appears there are a few tools for migrating from a Gallery V1 but not a Gallery v2 installation.
The ones I did come across also seemed half complete, and either failed outright or didn't work at all.

There was one saving grace however, the flickr_upload CPAN module and a bit of coding made it relatively easy.

All in all -- I'm happy with the results of their flickr import. You're welcome to take a look at their photos.
They have some wonderful photos from trips in recent years around both Australia and New Zealand.

Here is just a collection of some of my favourite photos of theirs:



Now -- the only job left is to update their blog so the images point to Flickr instead of the Gallery2 location!
Unfortunately due to the URLs created by flickr, it's a manual process.

The joys of being the family sysadmin!
