This download.php file has a header for making the image with PHP GD Library and download the file like this
header("Content-type: image/png");
But google didn't crawl these images. Does anyone know the solution? I can't store these image in server.
回答1:
You don't mention how you are feeding the beast, so I suggest you start by providing google a site map via their webmaster toolkit. You can specifically list the images that you want crawled. Google provides good help articles to get you going.
回答2:
Google can't index images that are not stored permanently, I'm quite sure it can't even index images without context (i.e. which are not part of a describing/linking page).
回答3:
You can try to:
Send a cache header to allow caching of the image.
Rewrite the actual url to someting like: http://textscloud.com/get_img/download/VkZaU1FtUXdNVVZWVkZKT1ZWUXdPUT09.png (should match your filename header)
