This may sound like a dumb question,once your in google images,will google get all your images in google images in the end? Because i check every day how many images have been found by google images from my site,and it keeps getting more and more. So will ,in the end,google index all your images in google images,and is it just a mather of time?
If your site has enough pagerank to be fully indexed in google, all your images will also be indexed (unless you don't want them to, of course).
i am asking this because it seems like only the images on the pages that have been linked directly from my index get indexed by google images. Or will this just take longer?
yes ...google good crwel to images to any site if you want ...spieacilly if you let spider read images files from robot.txt
my dear ... robot.txt mange the crawel to go to your site ...if you deny it from craweling files such that ... ( .gif , .jpg , png etc ) so google not crawel images and this good for sites have specail images ... i hope it help you
