Make images dead

With 40 pages of questions, I’m sure this has been covered but I haven’t seen it. My client likes the look of the gallery but they are asing for a feature that I’m not sure about how to get done. Right now on the page https://www.gablesandgates.com/communities/ I have a galley set up. When you click the images you see a larger image. They do not want that, the want the image to be dead for a lack of better wording. Basically they want it unclickable.

Any help is greatly appreciated.
