RPG Maker 2k3 error: "Invalid Image Format"

[Invalid] Image Format

This happens when I try to begin a test play session.
What is the matter?

did you remember to place a starting character position?

Yep.

I don't know  I'm sorry  even if I saw it in front of me I might not know what to do either, well, at least I tried to help

No problem.

Hopefully someone can help me though.  :'(

EDIT: Turns out it meant that I was missing a file called vehicle from my charset.

Now I have a new problem though!

I get a message reading "[Invalid] Image Format" when I try to start up a test play.

to me that sounds like the .whatever the file is is wrong.  perhaps rm2k3 only accepts certain file formats and yours happens to be not the right format so it cannot read it

I don't know what that'd be. All of my charsets are in PNG format as are my maps.

I'm sorry, someone will have to take you from here, I just looked through all of my files and they too are all in png format... unless your computer cant handle pngs but that doesn't make since considering everything else works just fine.

oh well, at least I did try to help someone 

It's appreciated.

Yeah, the PNG files are fine.

edit: Turns out their was a faceset file that was buggy.

Problem solved.
