How to prevent error messages on front end of VM store

[Anthweb1]

I'm using VM3 and sometimes when images don't populate for my site I get the attached error at the top of the page. How do I prevent my customers from seeing it? I have the VM advance settings for (Enable debugging messages) as NO debug and PHP Developer Mode not checked. Any ideas?

Thanks,

That is a genuine error message. Looks like the GD library on your server is not configured to use .png files. Try using a .jpg image for this product.

Thanks for the reply but I don't believe that is the issue. The majority of the product pics are png and display fine.

Are you viewing the FE when logged in as superadmin?

Not easy to see against that green background, but there is a double slash in the image url.

Exactly which J/VM versions? http://forum.virtuemart.net/index.php?topic=79799.0

I thought it was happening with non Admin accounts but I just double checked and I don't see it when I log in as a registered user. I was only concerned that my customers were seeing it but apparently not. So I'm all set. Thanks for the help.
