Welcome to the Q&A Forum

I actually wrote something relatively recently which might be of interest to you: https://searchnewscentral.com/blog/2019/07/12/what-might-ai-machine-learning-image-experiments-teach-us-about-search/ The conclusion I basically came to was: "If I were working on an eCommerce store selling rolls of fabric, I’d say that an image of a rolled up bit of fabric would be good for a mechanical mind to interpret. A zoomed in image of just the fabric’s texture, would also be pretty good! A lady standing by a fireplace with a wine-glass in one hand and a fabric-roll in the other? That would be very difficult for a mechanical mind to interpret." Play with Google images. Type in your product (or competing products) and see which types of image gain the most prominent positions. That will give you an idea on, how advanced Google is in terms of interpreting certain objects. Do the images need to be super obvious with cut-outs against a blank background? Can you be more adventurous? Also look at the image thumbnails for your products (or competing ones) on Google Shopping. See what's doing well there IMO obvious is better for search algorithms, but then again may not have such good conversion rates as more adventurous creative
