(2k3)Custom Content help

How do you put custom content in rpg maker 2k3 or is it not possible. PLEASE HELP ME!

It depends on what you mean by "custom content." You can import your own sprites, tilesets, and such (or find some laying around the internet), but if you're thinking about scripting and CBS's, then 2k3 can't help you there.

no i just mean sprites (homestar XD )

Then the answer is yes. You can either make your own using paint (or some more sophisticated program), or you can download them anywhere you can find them. There is a good number of resources here (direct link: http://crankeye.com/resources/), and at Charas.net (http://charas-project.net/resources.php?wa=0&lang=en&area=2&offset=0&howmany=10&fsearch=)

Once you download what you want, go to the resource manager on rpgmaker and import whatever it is you got into the proper category.

okay i got the resources but it says eroor:invalid image size

That means you're either importing it into the wrong category, or it's 1 or 2 pixels off. If, for example, you have a charset sized at 144/287, you have to take it into paint and make the canvas 1 pixel bigger. That doesn't usually happen, though. Just make sure that if you're importing music, you click on the music file first, if you're importing a battler, click on the battle char set file, etc.

thanks
