Problem Loading Textures. Parameter is not valid.

Alright, I have a big problem.
While everyone else here is having their textures appear white, mine aren't appearing at all. In fact, to try and make them appear is making my game crash.

Here's the code.

I'm trying to import 4chan.jpg (don't worry about the purpose, it's safe) to the stage, however, I can't seem to pick the right file location, then C# tries to load hot-air and the game breaks.
Where on earth am I supposed to search when I want to open or access a file?

4chan.jpg is located in the same folder as the project file, as well as in the father folder.
