Help with PHP,mysql, db_________________________________________________________________________________________________________________________________________________________________________________________I have a project that I need to complete today I will explain in the chat, NO Rookies or low quality people do not bid, Thanks. Fixing Pricing 1. I can't seem to upload an image - is there a certain file type? When I try it says "the file you have uploaded is not an image? Beside the box can we write what image types are accepted (png, pdf etc) 2. When I go through the "empty frame" option, the frame image that appears does not match the frame that I have selected. For example when I click on the white frame, it shows a black frame in the sample image. 3. When I select a matt, the colour is also not shown within the frame - still just see white. 4. Can we change the last option of "Not sure which frame to order?" to "Order Mirrors" 5. It's probably too early but none of the checkout process seems to be working. Dont bid if your gonna end up changing the bid amount. Thanks.
