My site specializes in games,that is why I have to post a lot of pictures both in the body and the sidebars.but calling each image is an additional http request and slows page loading time.I'm using smart optimizer,phpspeedy plugin,minimized the image sizes,etc but nothing helped me save page loading time(wp cache,db cache are useless).people are complaining that my site is slow and I'm getting a high bounce rate.
so if I could use css sprites of images,that could help save innumerable http requests and page loading time.the only problem is that the images are linked and I don't know how to implement css spriting.So far I've been able to implement image sprites for my sidebar captions only.
In short I want to use css image sprite for all images of my site including header,background,body and sidebars and the ones in the body and sidebars are linked.Please help me,I've been looking for days to find a solution but didn't get one.
