Non (POT bitmap)? and other fun questions of T2D!

Hello all,

Will this is my first T2D post (although i read them a lot), so i thought i'd add to the praise and say well done to melv and josh on a fantastic game engine (espcially considering it's allegedly in EA ;))

Anyway, here's the Q's,

1. what does this message that appears in the console mean

'Non POT bitmap loaded wasting approx 44944 bytes of video ram!'

example code:

datablock fxImageMapDatablock2D(playershipImageMap)
	{
		mode = full;	textureName = "~/client/images/Test/PlayerWebSave";
	};

i've saved my image in Photoshop CS as a png via save as and save for web, but it still says it?

2. I've a 5 by 3 image (15 frames) and i want to load it as a animated sprite then play it, is the following right?

datablock fxImageMapDatablock2D(playershipImageMap2)
	{
		mode = cell;	textureName = "~/client/images/Test/Player Walk (15 Frames)";
		cellCountX = 5; cellCountY = 3;
	}

Also, the second sprite no longer shows?

$player[0] = new fxStaticSprite2D() { scenegraph = t2dSceneGraph; };
	$player[0].setPosition("420 300");
	$player[0].setSize( "40 40" );
	$player[0].setImageMap( playershipImageMapB );		
	$player[0].setFrame( (1+(getRandom()*14)) );

I'm migrating from DB Pro, so i'm a virgin c++ script/torquescript coder :), so be gental ;-)

Thanks in advance guys & gals, keep torqueing!
