Ashley - Always an honor to get a reply from you! Thank you very much - that seemed to solve the trick...setting the Sampling to Point. (I checked the Manual to get a better understand of what Sampling actually is, and it reminds me of the graphics settings on the Nintendo GameCube game, "Super Smash Bros Melee". It had the option to choose between linear and point graphics, and you could clearly see the smooth vs sharp pictures. This is very good information to know. Thank you again!
dinofun - Thank you! I have high hopes for it. And a lot of huge ambitions...lol I'm probably in over my head for my first game, too.
I hadn't messed with the browser zoom functions at all, and the other images up to this point were all well and good. I even use the same template when creating new character sprites. It was just that one sprite that was off for some reason. But all is good now!
