Shadey Theatre Episode 17: A Quest Begun, and a Comic Hijacked.
A few things about making comics in 2002.
Most people either used Windows 98, 2000, or a Mac. These OSes didn't have
the ability so save as PNG or do a good clean GIF.
(To this day Windows still can't process GIFs correctly.
Windows XP could save as PNG had been released at this time,
but most people only got it when they bought a new computer.)
On top of that most Internet browsers could only process JPG and GIF.
That is why most comics from around the turn of the century
are saved in those formats.
If you wanted to save as a GIF (which was better at maintaining sprite quality
than JPG,) you needed a paint program such as Photoshop or Paint Shop Pro.
Which I think explains why these comic tend to be so blurry, especially on the sprites.
I've had some experience with Adobe products in trying to make
sprite comics and I had similar results.
