Hi. (super beginner) I am trying to improve my design portfolio site ( http://corndogbrothers.net ) I added a css image pre-loader to speed up my image galleries, which works great, but now my opening page loads too slowly. I thought I had separated the image preloading so that images would load on each page separately, but it appears to be happening all at once. Any help or tips would be appreciated. Current preload code from one page below:

.xSection-magazines:after {
content: url(http://corndogbrothers.net/storage/media/magazines5/cb_frame2.jpg) url(http://corndogbrothers.net/storage/media/magazines5/cb_frame3.jpg);
