Quite laggy as expected... But, at least it's possible!
To add your own image: 1. Reduce your image's dimensions. If you don't, it will lag even worse than the example! I recommend ~150x150 px. 2. In the code, set "image size x" and "image size y" to the image's size. 3. Convert the image to a file with a list of hex codes separated by newline characters. 4. Show the "image" list, import the file, and hide it. 5. Test it out! If it appears to big or small, adjust the "res" variable.
