amwps If it is a large picture, it will be enlarged when you click the enlarge button, and you cannot control the free scaling of the picture. It is very useful to use the scroll wheel to resize the picture on the computer.
Did you try it with trackpad though? All Mac's and most Windows laptops use trackpad. When users attempts to scroll with trackpad, the image will zoom, and the user can't navigate the zoomed image with normal trackpad gesture any more. You should try.
Although I could add an option, Files Gallery does not use this version of Photoswipe with wheeltozoom
. Perhaps I will upgrade in a future release at some point.
