I tried the code listed.

I have about 800 items and only about 20 have an image so for, New Store I'm just setting up.
I got a message "No missing images identified." and I guess that is because the products do not yet have an image specified.

Is there a similar easy way to find what items do not yet have a picture? I have about 2,000 items to do total eventually.

Also how do I bulk upload my images and get the products to find them. I am sure I am missing something easy?
At this time I am trying to go through 1 item at a time and enter the image. Images have the same name as item number. So if myproduct123 is the item number then the image is myproduct123_400.jpg
I have read that if I used a base name such as myproduct.jpg Zencart would use all images of that base such as myproduct123_400.jpg and myproduct123_400BK.jpg etc.. for extra images, but that is not working either for me right now. I use myproduct123.jpg and the image is not shown, it is only shown when I use the full name myproduct123_400.jpg

I can bulk upload all the images into /images but do I really have to go through each item one at a time in category/products to add them?

Thanks
