You aren't by any chance interested in separating that, in hosting a server which gives a link to a good flickr image when given a word? I searched for something like that and in the end stayed with my ugly approach of parsing flickriver for getting a random image from a hard-coded group with a fitting topic.

Flickr already does this if you use their search API. The Flickr part of the script in my Github repo has an example.

As far as I understood, you need a Flickr API key for that. My software runs locally, meaning keys are not practical, I want the configuration to stay simple. But seeing how simple the code is I'll just have to get over it and host this as a service myself. Thanks for the example, still very useful.
