UPDATE: Dave Kellam, the author of flickrRSS, sent me an e-mail shortly after I put this post up to let me know that he reads my site and to thank me for the plugin plug (well deserved Dave). He also expounded on his future plans for the plugin and his intention to take care of its inability to display Flickr's "medium"-size images (500 pixels wide), my only complaint. Then, not two hours after that first e-mail, he sent me an updated PHP file that addressed the "issue" (you can now see the larger pictures on my photos page). I'm told that he'll release this version to the public in the next week or so.
Ever since the latest site re-design (and even before), I've been a little less than pleased with my photos page, which basically contained just two links, one to my Flickr photostream and one to my PHP Slideshow script. I have a couple of ideas to help fill in this space, but haven't had time to implement them. I was either going to use the Flickr API to populate the page with the most recent photos or run the Flickr RSS feed through an XSLT transform to accomplish the same.
However, while doing some very cursory research I stumbled across flickrRSS, a WordPress plugin. To be honest, I didn't have high hopes for it and never expected to actually use it, but after setting it up it was hard to convince myself that it wasn't exactly what I needed. The available customization options, image caching, and integration with the WordPress panel have really sold me. The only thing I will probably hack it to do is to pull medium-size images (500 pixels wide) instead of the smaller sizes it currently supports.
Truth be told, I'm a little bummed that I found this because building it myself now would likely be re-inventing the wheel.
