[Plugin: Share Buttons by Lockerz / AddToAny] Use CSS sprites for standalone share icons
At the moment, separate icon image files are loaded whenever any standalone services are chosen.
Performance can be improved by combining all of these icons into a css sprite. Whenever the admin adds/removes standalone services and hits Save, this should trigger the creation of a CSS sprite including icons for all the selected standalone services.
There are lots of free web services for creating sprites, and many of them offer APIs as well…
I understand that there are a couple of services for which sprites can’t be used – Facebook Like, Google +1, etc. But the rest can and should be combined into a sprite.
