Can anyone please let me know how to add additional images to a product. I already have an image with Small Image, Base Image, Thumbnail radio boxes selected and I want to upload another or additional image for that product without selecting all the 3 radio buttons. Thanks
From the images tab you just need to browse for the image who wish to add and click the Upload files button. For the additional image you do not have to select any of the radio buttons.
If that is not the issue we would need more detail.
Maybe the issue is with the template file on the product view page? Is this were you expect to see the additional image. Turn on template path hints to see what template file is being called, probably template/catalog/product/view/media.phtml, there maybe an error in your code here.
