For SEO reasons I am sending some images using PHP readfile
and URL rewrite
. I save images in a folder with numerical id (id.jpg)
but serve the image with keywords (some-seo-word-id.jpg
). While the scripts runs smoothly and show images effectively, however in pages with multiple images (5 to 6) it fails to send all images correctly.
Refreshing the pages 2 to 3 times sometimes shows all images, sometimes it does not ! Since the max image size delivered using PHP readfile
is 70-140 KB each I highly doubt that memory can be an issue. My question is
- Is there any better approach to this only with Apache
rewrite
. - How does Facebook deliver all images effectively with php ? There url are something like this
https://www.facebook.com/photo.php?fbid=XXXXXXXXX27&set=a.4533609xxxx.xxxx099.xxxx210426&type=1&theater
- will server side caching in binary format help ? To me this should not affect much as
readfile
of an image or cached file will still read a particular file (cached file instead of image !)
