My impression is that you need rather more than less, and that the indexing 
itself is hard to do efficiently. As PHP is not among the fastest languages 
under the sun, I doubt that a pure PHP solution could/would be a good idea.

However, as usually PHP folx build on MySQL, it might be an idea to build your 
query processor on MySQLs full text search capabilites. This would be tricky 
and fun, and I doubt that anyone has done this so far. You would be able to 
use GIFT/Viper's ideas almost all the way. All you would need for this would 
be a bit of image processing in PHP, some of which you doubtlessly delegate 
to some PHP image magick type of library, anyway. If you are interested in a 
more detailed idea on this, please do not hesitate to contact me for more

I hope it helps :-)
