ok here is the sizing algorithm that will go into testing

if ($actualWidth>$actualHeight) {
	if ($actualWidth > 350) {
		# scale height to max width
		$displayWidth = 350;
		$displayHeight = int($displayWidth * $actualHeight / $acutalWidth);}
	else {
		$displayWidth = $actualWidth;
		$displayHeight = $actualHeight;} 
} else {
	if ($actualHeight > 450) {
		# scale width to max height
		$displayHeight = 450;
		$displayWidth = int($displayHeight * $actualWidth / $acutalHeight);}
	else {
		$displayWidth = $actualWidth;
		$displayHeight = $actualHeight;}
}

One of the advantages of rich text editing is that you can paste code in the window :))

One prob is that i can apply that easily to uploads, but it would need to be installed deep in the rte code for pictures off the web ... oh well, just another challenge
Seth says
Note that there is no distortion taking place here. It either leaves the picture alone, if it will fit, or it scales it to the width, if that is where it does not fit, or it scales it to the height if that is where it does not fit.

this algorithm has been deactivated, see 2815.
