Image results in Solr Search

[Jagdish Kumar]

Hi
 
I am trying indexing and searching various type of files in Solr3.3.0, I am 
able to index image files but it fail to show these files in result of any 
search operation.
 
I am not aware of how Solr works for searching images, I mean it is content 
based or meta data based .. I am not sure.
 
If any of you have done Image Searches with Solr , I request you to please help 
me out with this.
 
Thanks 
Jagdish
