Series of images for eLearning

I use the same strategy as Tom. Depending on the image library, you can sometimes search for images with the same model or in the same series.

However, for people with disabilities, it's going to be challenging. Getty images actually does have some decent ones like this woman or this short series. When I needed images for disabilities, I found I sometimes had better luck searching for specific disabilities or assistive technology/mobility aids (cerebral palsy, leg brace, hearing aid, Downs syndrome, etc.).

Disability Images would have better options for you, if you have the budget. https://www.disabilityimages.com/

None of the usual character cutout library options are good for disabilities. It's mostly obviously able-bodied models pretending to use cheap wheelchairs.
