my site is http:www.xertionfitness.com. I been having this issue for some weeks now and i need some help.
I have maxcdn, i've upgraded to a vps. I have firebug wih firefox. I dont know what im doing wrong when it come to specifying these images below.

when i use firebug, i get this class for the images dimension 640 x250 in the feature slider.
When i check gt metrics or pingdom.com it still show the same images that need to be fixed. what am i doing wrong? what could be the reason that its not showing up in the testing sites?
