I’m experiencing a similar problem.
For me, I am successfully able to upload images via the Admin Panel > Catalog > Manage Products > ... > Images Tab.
It will display there upon successful uploads.
When I upload multiple images the same way, the rest of the pictures wouldn’t appear under the “More views” on the front (customer) end of my website. In addition, even if I set the 3 options- “Base Image”, “Small Image” & “Thumbnail” to other images, somehow the old picture remains there under “More views” like as if its some sort of a “ghost” image. When I click on the “ghost” image, I will not be able to go back to the new image.
What’s puzzling is that I have successfully uploaded multiple images for certain products in the past. For those with multiple images, they are currently displaying on my website’s front end as expected. I tried flushing cache, switching options and the php.ini trick, but they didn’t work.
I have no idea how to solve this. I have been googling non-stop for many hours for possible solutions but to no avail. If it helps, I did notice a notice on the Images tab:
Image type and information need to be specified for each store view.
Any help would be gladly appreciated
