You can write your own module that handles metadata extraction, using some external libraries. For the moment, I don't think that this is something important for the core, so unless someone provides a patch (or sponsors one of the developers to do it), it shouldn't be implemented any time soon. It is related in the sense that it can index this metadata, if obtained from another module, so that you can query it using the Lucene plugin. For example, once you get the dimensions of a tiff image, you can store this information as fields of the indexed item, and then query all images with a width between 600 and 800 pixels. -- Sergiu Dumitriu http://purl.org/net/sergiu/
