Good day all, I am trying to make a application so that I can do some basic edits on photos. I have binded a collection to a listbox and I can get all my text information to populate but I cant get my image to show. Every example that I see sets the image by using a uri, however, I didn't do that to create my image and I'm not sure if that is why. I do know that the image appears to be loaded correctly as all the properties about the image are shown (height width pixals). I believe I deleted all the code not related to the issue.
Thanks in advance, Chris
