What does Imageproxy.php do?

[SJ77]

Noticed script imageproxy.php using a lot of my server resources.

Wondering what it is for?

Thank you

not sure that helps me.

imageproxy.php is lowering site speed for me, causing random 502 errors as well when it overloads my system. Should I turn it off?

What can happen?

I did test - when one image is loaded to the proxy - the time that is loaded is two times greater than during charging of the direct link.

I turned off the 'Serve images from local server?'

There is a bad news - all published images including serving on a local server must be manually edited link.

It is possible that the support caching to help, but at this point my test site is alfa version and I have not the support caching.

I notice the time issue also, if I turn it off..

How about the non ssl image links, causes this security alerts ?

I personally am skeptical on ssl. Too many restrictions on freedom of the Internet space ... If all sites switch to ssl, then surely invent ssl² ha ha.
However admin / site owner should do periodic tests and to monitor their community.
