Album Images appearing in, for example Google image search

I am over at http://www.johncoxon.com ( my main website) but usually access and upload to my albums using http://www.johncoxon.com/gallery (as the person I paid to set up my website matched it with Mambo and I can no longer pay for development and don't know how to work mambo.) Problem is that individual images from albums do not appear in websearches and I am wondering if this is something I could put right.
