[Feature request] clickable portfolio screenshot

[MarcoIeni]

Portfolio screenshots are quite small. What about making them clickable in order to see them at full size?

I found https://photoswipe.com/ javascript library that has no dependencies.
the demo on their website is really nice, this is what I have in mind.

I found this https://www.xianmin.org/hugo-theme-jane/post/image-preview/, that integrated https://github.com/liwenyip/hugo-easy-gallery project, which ports this javascript library to hugo.

@MarcoIeni that would be nice to have, unfortunately, I haven't had enough time recently. Anyone who are interested in this feature could make a PR.
