Having a pretty constant issue uploading photos.

I take the photos in a pure white light box; edit the sides from the box off and I'm left with product on a white background.

I attempt to upload these images and amazons system immediately kicks them back telling me my products that are very much clearly on a white background ... need to be on a white background.

Any ideas how to fix this issue? It's a horrendously bad feature that keeps kicking back the product images.

Is it better to use Amazons A+ content modules or include images as recommended by Amazon gurus on youtube? Do images impact Amazons ability to search and rank vs text in the module?

My product listing had 9 images, but now only the main photo is visible. In the listing settings, all the images are still there. The "A+ content" is still displaying as usual.

What could be the issue, and how can I fix it?

I sincerely hope for your help!
