Hi
I've installed IH2, changed my directory permissions correctly, and have the correct PHP configuration. ZC v1.3.8a.
But, whenever I upload a PNG, I get errors related to the preview of that image.
Warning: imagepng() [function.imagepng]: gd-png: fatal libpng error: zlib error in /home/oleoadmin/oleo.co.nz/includes/classes/bmz_image_handler.class.php on line 646
Warning: imagepng() [function.imagepng]: gd-png error: setjmp returns error condition in /home/oleoadmin/oleo.co.nz/includes/classes/bmz_image_handler.class.php on line 646

By preview, I mean in the admin section under the Manager and Preview tabs. In the Manager tab, the PNG preview for each size is blank, although the image has been confirmed as successfully uploaded. And it has. It shows up on my product page just fine.
On the Preview tab, the preview sizes for PNG are tiny dots, not the actual sizes like the GIF and JPEG previews.
Plus, there's that disconcerting error message.
BTW, the GIF and JPEG uploads and previews work perfectly.
I'm sure I'm not the only one who's had this error.
I've uninstalled and reinstalled IH2 a couple of times, and cleared the image cache. Also, I have no other image handling plugins.
Any thoughts?
Thanks in advance.
