Hi. I hope you'll bear with what I'm sure is an extremely naive question or two. I recently uploaded virtually all my images to a subdomain - so the images are housed at images.mydomain.com as well as mydomain.com/images, and I have about 50% of the images being pulled from the subdomain and the other 50% from the subfolder.
My two questions are:
1) Do I need to submit a sitemap for the subdomain in order for these images to get indexed or will they simply be 'found' along with the crawling of the web pages? In other words, will Google (or other search engines) follow the subdomain image url and index the image without further interference from me?
2) If/when the images are indexed, will a person conducting an image search still have the option to visit the web page where the image appears, or will they be shown simply the image, all by itself, on an otherwise blank page?
I have a smallish website that, as of this writing is only partially indexed, but the few images already indexed account for a good portion of the minimal traffic I'm receiving thus far. I don't want to shoot myself in the foot any more than I already have.
I know this isn't the most coherent of explanations but I'm hoping that after the laughter has died down, one of you extremely knowledgeable individuals can jump into the Way Back Machine, dial it back to the time when you didn't know your .htaccess from your robots.txt, and understand the questions I'm attempting to ask.
And thanks to you all. I've been lurking here for awhile and I don't understand half of what's discussed but I've learned a ton of things nevertheless. Every last one of you has been a tremendous resource for me already.
