Very funny, 600 already has the code for standby images.

PS
Update: yep, works like a charm. You can use this code (mostly shamelessly copy pasted from 350) to draw centered image, just replace this.x .y .width .height .color with 0 0 600 800 Color.black:

Spoiler:

	var window, path, bitmap, temp, port, x, y, bounds, ratio, width, height, ditheredBitmap, color;
	window = this.root.window;
	path = "/Data/logo.png";
	if (FileSystem.getFileInfo(path)) {
		try {
			bitmap = new Bitmap(path);
			temp = new Bitmap(this.width, this.height, 12);
			port = new Port(temp);
			port.setPenColor(Color.black);
			port.fillRectangle(0, 0, this.width, this.height);
			x = 0;
			y = 0;
			bounds = bitmap.getBounds();
			ratio = (bounds.height > bounds.width)?this.height / bounds.height:this.width / bounds.width;
			width = Math.floor(bounds.width * ratio);
			height = Math.floor(bounds.height * ratio);
			if (height > width) {
				x = Math.floor(this.width - width) / 2;
			} else {
				y = Math.floor(this.height - height) / 2;
			}
			bitmap.draw(port, x, y, width, height);
			bitmap.close();
			ditheredBitmap = temp.dither(true);
			port.close();
			temp.close();
			window.drawBitmap(ditheredBitmap, this.x, this.y, this.width, this.height);
			ditheredBitmap.close();
		} catch (ignore) {
		}
	} else {
		color = window.getPenColor();
		window.setPenColor(this.color);
		window.fillRectangle(0, 0, 600, 800);
		window.setPenColor(color);
	}
