As the description states, I have been trying to figure out a way to make a gallery responsive. I noticed on my smart phone when I would access our wiki, the gallery as displayed on any given page per the Gallery Plugin was not collapsing, thus leaving much of the gallery unseen and to the right of the viewing window of the smart phone, or for that matter on any device that renders your site less than actual.
After a bit of searching and Googling, I stumbled on this terrific source for making your gallery using the Gallery Plugin, responsive. See this link at
https://github.com/splitbrain/dokuwiki-plugin-gallery/issues/58 and go down to the last post by Wishbone1138 and that post spells it out perfectly. I followed the suggestions and I now have a fully collapsible gallery for smaller devices and viewing.
I contacted our host and requested they install ImagMagick's convert tool, they did it in seconds, and I then followed the rest of the suggestions as outlined at the link I provided.
Now that being said, the suggestions do not make the individual images truly responsive, but they do collapse as your screen is reduced, so see an example you can view our homepage at
www.thepatriotwoodwiki.org and try collapsing your browser window, nice right!
I'd like to thank Wishbone1138 for the great tip, and Andreas Gohr for the great plugin.
Note: for my host
https://www.a2hosting.com/ the path to the ImageMagick directory is /usr/local/bin/convert, you'll need to install the path at your Configuration Settings panel.
Here is another handy link by Dokuwiki on the subject as well

EDIT Upon re-examining the above suggestions, you do not have to install ImageMagick in order to make your gallery collapsible. I believe the key is setting your rows to display image to "0" in the Gallery Plugin settings. I have disabled the ImageMagick by deleting the path in Gallery Plugin settings, and the images still collapse.
The reason I revisited this is after I read:
Be carefull when using ImageMagick with many or large files (i.e. when using Gallery Plugin). This can generate a high load or even freeze the server. In comparison, libGD is limited to PHP's performance settings and should be safe to use.
