APPCRASH on wpfgfx_v0400.dll only on 32-bit systems - wpf

Question

I have an issue with a WPF application that I'm writing. I have a window that I load with profile pictures for the user to choose from when setting up an account within the application. Each picture is loaded into a user control, and placed in a stackpanel, so that when the user clicks the picture, it triggers the code in the user control, and automatically sets their profile picture without any more clicking needed. This window loads on 64-bit systems just fine. However, when loading on a 32-bit system, the entire application crashes. The faulting module is wpfgfx_v0400.dll. I don't know why it's crashing. Please help.
Here's the error in the Event Viewer:
Here's the XAML on the frontend of the window in question:

I've researched what could cause issues with this particular dll, but none of it seems to relate to my issue.

Answer 1

So, I figured out the issue. Apparently, the size of the images that I was trying to load was too big. The images were all 2048x2048 pixels, which made them anywhere from 180 KB to 380 KB in size. Apparently this is too much. I resized all of the pictures to 100x100 pixels (as I was only ever presenting them to the user as 100x100), which brought the file sizes down to 7 - 10 KB each. After that, they loaded just fine with no crashing issues.
