We're uinsg SitmapGenerator 4 -and are excited by the new "Map Images" function for Googles new image sitemap function!
We've already excluded all nav / system image directories.
However, our Content Images (i.e the ones we actually want to index) are stored on a subdomain - i.e images.site.com, whilst SMG is told to spider site.com.
Is the best way to index these images to simply include that sub url - or is it possible to only index / crawl those images when called / linked from the main site?
How would I do this, tell SMG to include the entire subdomain (images.site.com) in the sitemap for site.com, or perhaps just follow links to that subdomain, i.e spider only images linked from the main site?
