Socializer plugin conflict:
Socializer plugins puts this CSS rule:
.postbox is a WordPress class used to wrap quite a lot of stuff. That rule the plugin adds makes all images inside of .postbox disappear when .postbox is hovered. AAkash should have made that rule a bit more specific to his part of the plugin.
Let AAkash know about that, i'm sure he'll fix it.
Conflicts with some themes (Nuance is one theme)
