anyakaats,
I’m not the plug-in author, but I did make that snippet above to target some things but not others.
Does the page in question have its own class? “Home” is built into most themes, as is “blog” and “single,” and most Genesis themes allow for you to very easily add one on a per-post or per-page basis.
Otherwise, you might want to lean on the container for the specific content, which may be something like “#gallery-1” if it’s a default WordPress gallery.
Either way, I am reasonably sure you can adapt what I wrote above to have a “not” selector in jQuery to deliberately avoid certain parts of the page, like this:
jQuery("body.home * img").attr("nopin", "nopin");
turning into this
jQuery("body.home * img:not(#gallery-1 dl dt a img)").attr("nopin", "nopin");
or
jQuery("body:not(.gallery-page) * img").attr("nopin", "nopin");
I may have a chance to test this tomorrow when I get back to work, otherwise it may be worth a try unless someone comes around to correct it, if need be.
