This is faster than asking to return a full image each > time. but slower 'cause for each image you need to requests On the other hand, file_get_contents could return false positives cause the fact we are asking for an image does not mean an image will be returned. I would go for a curl call, where you can have both headers and content so in one call you can handle every case. A bit slower than a HEAD request, surely faster than a HEAD request plus the REQUEST. One more thing, I hope you have rights to grab these images, usually there are APIs or webservices when a website would like to share images in this way but it does not seem the case here ...
