ok but

I tried it while I don’t really need it as I use tinypng which does the job, as I have few pics on my wordpress I haven’t optimised I downloaded this plugin.

It really forces you to pay which is annoying but just using it normally it’s ok

they are pics altough that it can’t work cos it says : Skipped (1.3 MB), size limit exceeded

so I’ll make sure I use tinypng first each time to avoid that message

thanks
