i am having a problem with png images. i can't use them. in the admin section i get this error:


Warning: imagepng() [function.imagepng]: gd-png: fatal libpng error: zlib error in /home/skinze1/public_html/includes/classes/bmz_image_handler.class.php on line 646

Warning: imagepng() [function.imagepng]: gd-png error: setjmp returns error condition in /home/skinze1/public_html/includes/classes/bmz_image_handler.class.php on line 646

if i change the image to jpg, it works fine.. i also noticed that when i go into the 'preview' section in image handler for these images, jpg and gif show a rectagular colored image and the png shows a very small checkered box.
