Best Sellers / new product thumbs jagged!

[carbontwelve]

Here's how to amend that Advanced Guide article to do what you want.

Create a folder within your Site folder called "Thumbnails".

In your Mini Best Sellers Layout and Mini New Products Item, replace the line

<img style="border: 0;" src="<actinic:variable name="ProductImageFileName" />" width="75" alt="<actinic:variable name="ProductName" encoding="strip"/>" />

with

	<actinic:block php="true" >
	// START Create a thumbnail image t_nn_ProductImageFileName - V 1.04
		$nScaledWidth = 75; 		// scaled image width
		$sOriginalImageName = str_replace('\\','/', '<actinic:variable name="ProductImageFileName" encoding="perl" selectable="false" />');
		$sThumbImageName = 'Thumbnails/t_' . $nScaledWidth . '_' . basename($sOriginalImageName);
		list($width, $height, $imagetype, $imageattr) = getimagesize($sOriginalImageName);
		switch ($imagetype) 
			{
			case 1:
				$image = @imagecreatefromgif($sOriginalImageName); // Attempt to open GIF
				break;
			case 2:
				$image = @imagecreatefromjpeg($sOriginalImageName); // Attempt to open JPG
				break;
			case 3:
				$image = @imagecreatefrompng($sOriginalImageName); // Attempt to open PNG
				break;
			default:
				$image = NULL;
			}
		if (!$image) 
			{ // tell what failed
			echo "<br><font color=red>Thumbnail creation error opening: $sOriginalImageName </font>";
			}
		else
			{
			// Get new dimensions
			$t_width = $nScaledWidth;
			$t_height = round($height * ($t_width / $width));
			// Resample
			$thumbimage = imagecreatetruecolor($t_width, $t_height);
			imagecopyresampled($thumbimage, $image, 0, 0, 0, 0, $t_width, $t_height, $width, $height);
			if ( ! imagejpeg($thumbimage, $sThumbImageName) ) 
				{
				echo "<font color=red>Thumbnail creation error saving: $sThumbImageName </font><br>";
				}
			else
				{
				echo "<img src=\"$sThumbImageName\" width=\"$t_width\" height=\"$t_height\" border=\"0\"";
				echo ' alt="' . htmlspecialchars('<actinic:variable name="ProductName" encoding="perl" selectable="false" />') . '" />';
				}	
			}
 	// END Create a thumbnail image t_nn_ProductImageFileName
 	</actinic:block>

Change the line

$nScaledWidth = 75; // scaled image width

to suit the width you want.

This helped me a ton, the old php script from the downloaded advanced manual broke with the upgrade to v9, this one works a charm!
