Flickr seems to be blocking my blog’s image requests, resulting in the broken images you see to your left. This blows. I’ll try to rectify this tonight.
Update: Ok, I figured out the problem. Flickr used to pass the URL to the full-sized image in its RSS feed, which I would then parse and use to build the URL for the thumbnail. Now, they’ve changed the feed to pass the thumbnail URL, so the URL that my code creates is invalid. I’ve fixed the problem and will update the site tonight.
