I am trying to pass an image to the display through the GxEPD module. I tested the display and its working fine with an example sketch.

When I add any other image after converting it to hex values, this happens:
This is the image in GIMP:
And this is what the display shows:
As you can see, the display shows the image glitched a lot. It looks a lot like each "row" of a few pixels is mirrored horizontal. The question here is: Why? All I did was converting the image in GIMP to .xbm, taking the content, stripping whitespace, pasting the Arduino syntax around the code and replacing the example file with this one.
