Image Title & Alt Text – how to avoid keyword stuffing

I am developing our company website which will eventually feature a few hundred images of the same few products. I want to optimise each image with a Title and Alt Text but I am concerned that if I add a meaning description it will appear as keyword stuffing.

The products lend themselves to synonyms i.e. the overall product category are known as mobile billboards or advertising vehicles and they comprise product descriptions as follows:

Product 1 – Advertising Van, Ad Van, Advan, Van Advertising, Poster Truck, Truck Advertising, Poster Van
Product 2 – Advertising Bike, Ad Bike, AdBike, Bike Advertising
Product 3 – Advertising Trailer, Ad Trailer, AdTrailer, Trailer Advertising

In most cases, the most descriptive title would be something like ‘Advertising Van operating in London’ or ‘Ad van promoting Amazon in Liverpool’

Can you tell me the best approach to avoid the appearance of keyword stuffing in the Title Text and Alt Text?

Thank you in anticipation.

David.
