Available in https://github.com/tiddly-gittly/tiddlywiki-plugins/releases and CPL
Easy to use, try drag some image import to https://tiddly-gittly.github.io/tiddlywiki-plugins/#%24%3A%2Fplugins%2Flinonetwo%2Fgallery and use
<<gallery filter:“[all[]suffix[.jpg]]”>>
to load them (Better to use .webp, it works better than jpg in modern browser)
I created this because I want to add tags to images
And open image from gallery
