Hi, As Lewis say before, if you are going to use nutch for image retrieval and indexing in solr, you'll need to invest some time writing some tools depending on your needs. I've been working on a search engine using nutch for the crawling process and solr as an indexing server, the typical use, when we start dealing with images we became aware that nutch (through the tike project) extract to few information about the image "per se" (basically only metadata, gets extracted), I think that this is the biggest problem with nutch. One particular requirement for me was to show a thumbnail of the image, so I wrote a plugin that generates the thumbnail, then encode it using base64 and store it in the solr index. Other need was to annotate the image with the surrounding text to improve the search, I also write a plugin for this.
Summarizing, nutch it's a very good start point, but depending on your particular needs you'll have to write some plugins on your own.
