david_prentice:
You must have started with a JPG or PNG of your eyeball.
It is simply your use of a PC program to create the bitmap as a C array.There are several formats for the array e.g. XBM or regular BMP.
Then you use the appropriate method to display it.Post a link to the original artwork or just insert the image to your message.
From memory, the tutorial shows you how to create the C array.

Hmm... I did what you'd described above (started with a JPEG/PNG and used GIMP to convert the file to an XBM), then I inserted the C data array as described in the tutorial reference manual. Where I think I may have messed up is actually the syntax in my use of PROGMEM, as I opened up another project Im working on (a diy arduboy) and the answer was looking me right in the face, provided the syntax used in that library is typical of others. I dont mean to overly complicate things, but seems I had that line of code wrong, so im gonna try to change that around before uploading the original images and trying again. Will update here shortly.
