Bit of background - I'm currently working on an ecommerce clothing site specifically with an older age range (50+). Historically the company has always used flat jpgs to display product images on across the entire site.
We have recently started investigating the use of GIFs to display the products.
The question is, how do I best communicate this to the user? I had the simple idea of having a standard play button icon overlaying the image on a PDP (product description page). This won't be a video with sound, just a 3 second GIF of the product spinning around (as an example). I want to be able to convey to the user that a product has a GIF available to view on the PLP (product lister page) without literally saying "GIF available" as some people may not know what a GIF is.
