Forum Image rendering issues with Chrome

[محروم.كوم]

Hi. Some members who're using the google chrome browser to access our vb4 board (http://www.hmandsforums.oliwy.net), have PM'ed me and said that they cannot see the images located in the doc background and forumhead background slots on our forum. I have a red wall paper for my doc_background, and a cat strip image that says DEADICATED TO HORROR for my forumhead background. (both .png I think). They've said they can see the images fine on IE8, but not google chrome. In Chrome, the doc background is just a white space, and the forumhead background just shows as black with no design. How can I solve this issue? __DEFINE_LIKE_SHARE__
