Since your website is live and running e-commerce, I suggest the following things:
1.) Create a staging area, where we could deactivate all the plugins and themes for testing purposes to find the culprit.
2.)Check if the issues still persist, If no, we will activate the plugin one by one to find the culprit.
3.) Once we are able to determine the culprit, we will apply the changes to the live site.
I also found out that the image URL is changing to another src URL. See the screenshots below.
On my Chrome Desktop, the amazon image is working fine.
On my firefox and Microsoft Edge, the images URL changes to a new URL.
The correct image path to show the image is https://d2ldlvi1yef00y.cloudfront.net/us/live/apa/orange/medium/button_T6.png but somehow on the IE and Firefox or other browsers it was changed to https://d2ldlvi1yef00y.cloudfront.net/us/live/apa/orange/medium/button_T15.png
Let us know if you have already a staging area so that we can help you with your problem.
