I have added my site to GOogle Webmasters.

Issue is the site index stick to 3/4 indexed status in Webmaster Tools.

I had my previous wordpress indexing daily of albums but since I migrated to ZP and submitted all links it just indexed 4 and reducing.

I noticed it is not indexing albums or images.

We had this before and I am quite sure it is because you don't use a image page mod rewrite suffix:

http://www.wildart.in/accentors/rufous-breasted-accentor/rufous_breasted_accentor_1dx_3448.jpg

This URL looks like an direct link to an image but it is to a php page. So probably Google rejects it as a php script masking as an image therefore for security reasons. Try using a suffix to see if it makes any difference. If you search our own site via the googlge image search you find it quite well indexed.

Also check your robots.txt. If you maybe use a default one from older ZP releases that was set a bit to strict.

Otherwise we need concrete info from Google why it does not index.

Yeah, I used a image page prefix of .php and Google has indexed my galleries just fine.

Hi
Where do I change in a me.jpg to image.jpg.php?

You can fill in [i]php[/i] here:
Admin -> Options -> General -> URL options -> mod_rewrite suffix

oh but then all the url's are becoming non seo friendly

I doubt that that makes any real difference. The url maybe part of it but the content is what counts. Our site's images are well indexed and you can always use the sitemap plugin additionally.
