How to increase the performance of WPF Application

Question

I have developed WPF Application. In that application iam loading 200mb photos to the listbox.After that Iam adding those images to canvas.While adding photos to canvas after sometime (i.e; after adding 10mb images)iam getting Some error like ----

*****The CLR has been unable to transition from COM context 0x10b46f0 to COM context 0x10b4860 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations.*****

Is there any way to increase the performance of my application. I need a solution for this problem.

Any Suggestions for this.

Don't load all 200 mb of photos into the listbox all at once on your UI thread. Will the user be looking at 200 mb all at once? It'll take some work on your part, but you're going to need to do some delayed loading of the images from a background thread.
