A simple SSRS 2012 SP1 report with some sparklines rendered in the browser on the server doesn't return any of the charts (instead, it just shows an unfound image). Looking at the logs, I'm getting a "generic error occurred in gdi+", but when I looked through past posts, they were all on Windows 2008 and had hotfixes where the gdiplus.dll version was less than the one in Windows Server 2012 (6.2.9000.16384).
Any ideas on what's causing this, or how to fix it?
