Hello, I just used GTmetrix to test the performance of my site.

It is giving me these recommendations:


But I don't know how to do any of them to be honest. Could someone help me out?

I am currently using an Apart theme.

Set your image sizes that use IMG tag with a custom IMG MyCode.
Combine images using sprites is waaaay more work than is needed. Just switch out most of your postbit buttons to CSS buttons.
Optomize images... well yea.. not much you can do there for posted images... you may be able to use a PHP library to further optimize image attachments... but that's really overkill.
leverage browser caching is done via .htaccess codes.. I've seen a post somewhere on this forum which gave a perfect example of how to set caching time periods but I don't know where it is.
