I use IXQuick for any searches that I deem too 'private' to have Google know about. Political issues or anything relating to medical problems, for example.
IXQuick does not even record your I.P address and they offer a HTTPS connection for both image and text search.
I have no problems with advertisements, I don't see any. Might be because I block those kind of things with a modified HOST file.
