Already submited pull request for gallery: https://github.com/psychobunny/nodebb-plugin-gallery/pull/15
I see @psychobunny is active on this forums so i guess we wont have much problems with him applying that change.

Hook is merged ( https://github.com/NodeBB/NodeBB/pull/5828 ) so you can expect needed image plugins after 1.6 is released.

Yeah same here on fresh virtual machine. I think that its not like 10x 104MB. It's just single 104MB consumption, but why is htop showing it as 10 items i have no idea. Im guessing its because we dont know how to interpret htop output :)
If you add all percentages together it would be like you are using more than 100% of you r memory, which you are not (you can check that with other tools too). So, it's basicly 1x104MB, which is reall OK ammount of RAM to be used.

Just one question, is that 9 different NodeBB instalations running?

Link to forum / test topic would help.

Oh and BTW same thing can be used in other plugins that are trying to implement gallery like behaviour. They all need ability to add code to image link and this hook enables that so if it gets into master i think that we will see more working plugins in near future (if they are not abandoned by their mainteiners).

You have to do three things.

1. You have to use public/src/client/topic/images.js from my commit that i hope will get into nodebb master
2. and you have to install https://github.com/psychobunny/nodebb-plugin-gallery
3. and you have to change "action:ajaxify.end" (line 4) inside this file: https://github.com/psychobunny/nodebb-plugin-gallery/blob/master/public/lib/main.js to "action:images.loaded"

Basicly what you do is: 1) create new hook inside nodebb and 2) use this hool inside already available plugin that does not work without that new hook.

If hook i submitted gets into master, i will submit change to that plugin too. If it doesn't get into that plugin ill create my own and put it out in the wild.

You can see it working here: https://bitcoin-hrvatska.com/forum/topic/7/testna-tema

Lightbox plugin situation could be fixed soon.

Main problem with all plugins that are trying to implement lightbox like effects is that their options and/or changes are overriden by nodebbs on image loading / unloading.

I made some changes to my nodebb installation that enabled me to use https://github.com/psychobunny/nodebb-plugin-gallery

More info on: https://community.nodebb.org/topic/10960/opening-uploaded-images-in-modal-windows (there is working suggestion there that you can use untill something similar is implemented to nodebb)

If changes get applied, it will be really easy to update https://github.com/psychobunny/nodebb-plugin-gallery or any other similar plugin that applies lightbox effect.

Id like to change way emojis suggestions work too. For example if i want to use ":D" in chat i get offered :dagger" (in my instalation). So if i dont want that :dagger: i have to press space to get rid of that suggestion. If i just press ENTER ":D" gets replaced with :dagger:
Turning off that kid of actions would be nice.
