When adding a new product and trying to upload Thumbnail Image URL,although I'm able to select and upload an image (I select Full Size, then click "Insert in to Post"), it simply doesn't work. No image link appears in the Thumbnail Image URL box at all. So obviously when the product is viewed it shows the No Image thumbnail. Note: I'm able to upload images on my other posts and pages, but just not this one.
