@Tilen-Štraus Glad you got it working, and thank you for sharing your solution for others who may run into the same trouble 😄
Yesterday i did a post regarding thumbnails for images (https://community.nodebb.org/topic/8385/auto-thumbnail-resize-images)
I've been thinking
Would it be possible to show a static icon for all images in posts and when the users click on the icon the uploaded image will load?
We think uploaded images take to much space, and the nodebb-plugin-image-sizer is complicated for some users to use.
Any help/feedback would be appreciated
