[Problem with thumb images]

Thanks for the help!

 

This is where I have no idea what I'm doing... this is a site we had custom programmed. I know just enough PHP to be dangerous when it comes to this.

 

This is something my developers never really addresses/fixed - the grainy images.

[Problem with thumb images]

I have a new website where the thumb images display VERY poorly. I want the images to display clearly.

 

I think it has something to do with the $thumbfactor, but as I change it, doesn't help the quality.

 

Can someone look at this and see if you see any setting you would change to make the thumb images not so grainy/pixelated?

 

Thanks much in advance:

 

function getImage($srcImg,$typImg){

 

	switch($typImg){

	case 1://Thumb
		$cStr = "th_";	
		break;
	case 2://Prev
		$cStr = "pr_";
		nreak;

}

$abc = explode("/",$srcImg);

 $thumbName = $cStr.$abc[count($abc)-1];

 $abc[count($abc)-1] = $thumbName;

 $abc = implode("/",$abc);

return $abc;


}

function aspectRatio($width, $height ,$thumbFactor){
//-------Image Manipulation Constants---//
	$thumbFactor  = 110;
	$imageThumbPrefix = "th_";
//-------------------------------------//

		if ($width > $height){
			$retWidth  = $thumbFactor;
			$retHeight = $thumbFactor * ($height / $width);


		}
		elseif ($width < $height){
			$retHeight  = 82;
			$retWidth   = $thumbFactor * $width / $height;


		}
		elseif ($width==$height){
			$retWidth  = $thumbFactor;
			$retHeight = 82 ;


		}
		else die ("unknown scenario");


		$outStr = $retWidth.",".$retHeight;
//			$outStr = "100,100";

	return $outStr;
}

function aspectRatio_user($width, $height ,$thumbFactor){
//-------Image Manipulation Constants---//
	$thumbFactor  = 115;
	$imageThumbPrefix = "th_";
//-------------------------------------//

		if ($width > $height){
			$retWidth  = $thumbFactor;
			$retHeight = $thumbFactor * ($height / $width);


		}
		elseif ($width < $height){
			$retHeight  = $thumbFactor;
			$retWidth   = $thumbFactor * $width / $height;


		}
		elseif ($width==$height){
			$retWidth  = $thumbFactor;
			$retHeight = $thumbFactor ;


		}
		else die ("unknown scenario");


	$outStr = $retWidth.",".$retHeight;
//		$outStr = "115,115";
