Image Handler 2 (for ZC v1.3.8 ONLY) Support

[marksu]

I moved zen cart from subfolder to root.


Now I get error when zen cart trying to display the category products as list of images.

Warning: imagepng() [function.imagepng]: gd-png: fatal libpng error: zlib error in /home/...public_html/includes/classes/bmz_image_handler.class.php on line 646

error is in following code
$ok = imagepng($image, $dest_name, $quality);

Some reason some images does appear good but some it displays the error on.

I do have images uploaded in /images/ folder even images that gives error.
