Minimum number of images to upload

[cutting_edge]

First, I know the rules: We need to upload as many images as possible, up to 12.

My question is: what is the MINIMUM number of images that will still cause no harm from Cassini? 

I found no documentation about it...

If you upload one photo eBay will show a recommendation that you upload at least 2 more images.

Nobody has definitive answers about Cassini algorithms.

Three.

I have listings with just one photo, not all items need 3 or 12.

I guess you're right, but still, I hear that Cassini will degrade you if you have less than 4 images, some say 6 images, some say 3.

Does anyone have an "inside info" of how Cassini sees 1 image, 2 images, 3 images etc'??
