Zero, denada, zilch, nothing but here's a funny one for you if I do site:www.example.com/ I get 1 more image than site:www.example.com
are all your images getting indexed for the scraper site?
I wouldn't call them scraper sites, they are trade sites which have copied some of my images and serving themselves however they are strange names with a mix of numbers usually and guess what, I can't find one now!
For the regular SERPs everything is fine however I'm puzzled why G is indexing images from some of my sites and not others. A site I launched in November has every page indexed and ranking well, the entire Coppermine gallery is indexed yet not ONE image from the entire site seemingly is not in the index yet when I do a site preview all the images in the Coppermine gallery seem to be there yet the regular pages have some pages with images and some are missing!
Another site from July time had everything indexed almost immediately and all are #1 in the regular and image SERPs however subsequent image additions have not been added to the image results but are fine in the regular results.
Bear in mind I've changed nothing on my sites other than add CPanel Hot Link Protection with Google allowed and IP Deny. I have actually disabled these on one site to see if it is CPanel causing the problem.
This all seems to have something to do with me clamping down on hotlinkers, the sites have not changed however I stopped tens of thousands of images seekers and hotlinkers virtually overnight and then Google dropped loads of my images but not all.
I'm seriously considering testing with another host to see if that makes any difference whatsoever.
