Our site seems to be pulling in a lot of resources from our host, (we had to switch to a private server to avoid account suspension), so I'm working on trying to adjust some of the complications in our site performance / speed. We've been using the website (http://gtmetrix.com) as a resource for analysis and have been able to resolve a majority of the issues and get our grade up to a B / C... but we want A's across the board!!
At this point, we're being suggested to specify image dimensions as a primary concern. We've adjusted this in the actual html locations where these show up, but it looks as though a majority of the instances it is referring to is when we use featured images on pages and posts. Any suggestions on coding I could use that would help with this?
