Question

I there a way that i can cache the images coming from other websites? I want to have a local copy of the images using cache in PHP so that the site will load faster.

Answer 1

How do you know that caching the images on your server it's going to load faster? In fact, coming from other websites it's usually going to be faster (considering you're using a good image service) because you're going to Split Components Across Domains. You can of course cache your images and create some rules in your server configuration with subdomains to use parallel downloads, but keeping the images across different good domains avoids you from creating all this additional configuration.

If you plan to "load faster" your website, unless your images are coming from a slow server, you can ask other advices here and keep your img configuration. If you plan to cache your images for another reason, then we can have a better answer.
