Sure. Grab a copy of the specification for whatever image format you’re interested and write the read/write functions yourself.
Note that to write display functionality without an external library you’ll likely need to run your code in kernel mode to get to the frame buffer memory, but that can certainly be done.
Not that you’d necessarily want to do it that way…
