Here is this VS2010 Image Debugger Visualizer , for which someone sent a patch to work with VS 2012 . Download the 7-Zip package and extract it to <Visual Studio 2012 Install Directory>\Common7\Packages\Debugger\Visualizers. For me it was C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Packages\Debugger\Visualizers.
If you opened Visual Studio 2012, make sure you restart it.
