New project: Metapho image tagger

I'm excited about my new project: MetaPho, an image tagger.

It arose out of a discussion on the LinuxChix Techtalk list: photo collection management software. John Sturdy was looking for an efficient way of viewing and tagging large collections of photos. Like me, he likes fast, lightweight, keyboard-driven programs. And like me, he didn't want a database-driven system that ties you forever to one image cataloging program. I put my image tags in plaintext files, named Keywords, so that I can easily write scripts to search or modify them, or user grep, and I can even make quick changes with a text editor.

I shared some tips on how I use my Pho image viewer for tagging images, and it sounded close to what he was looking for. But as we discussed ideas about image tagging, we realized that there were things he wanted to do that pho doesn't do well, things not offered by any other image tagger we've been able to find. While discussing how we might add new tagging functionality to pho, I increasingly had the feeling that I was trying to fit off-road tires onto a Miata -- or insert your own favorite metaphor for "making something do something it wasn't designed to do."

Pho is a great image viewer, but the more I patched it to handle tagging, the uglier and more complicated the code got, and it also got more complex to use.

[metapho screenshot] And really, everything we needed for tagging could be easily done in a Python-GTK application. (Pho is written in C because it does a lot of complicated focus management to deal with how window managers handle window moving and resizing. A tagger wouldn't need any of that.)

I whipped up a demo image viewer in a few hours and showed it to John. We continued the discussion, I made a GitHub repo, and over the next week or so the code grew into an efficient and already surprisingly usable image tagger.

We have big plans for it, like tags organized into categories so we can have lots of tags without cluttering the interface too much. But really, even as it is, it's better than anything I've used before. I've been scanning in lots of photos from old family albums (like this one of my mother and grandmother, and me at 9 months) and it's been great to be able to add and review tags easily.

If you want to check out MetaPho, or contribute to it (either code or user interface design), it lives in my MetaPho repository on GitHub. And I wrote up a quick man page in markdown format: metapho.1.md.

Feedback and contributors welcome!
