Has someone use this php image optimizer (psliwa/image-optimizer) before? What do I need to use this library? Do I need to be able to access the SSH command prompt ? How to install optipng, pngquant, jpegoptim?
I have so many questions. Its documentation is not clear at all.
It uses optipng, pngquant, jpegoptim and few more libraries, so before use it you should install proper libraries on your server.
Help appreciated !
optipng, pngquant and jpegoptim can be installed via apt-get install command.
