for my panel, I want to load thumbnails from a local folder and display it on the panel, is this possible?
The pathway of the folder is e.g.: "C:/Users/User/Documents/Panel/img/ "
Well, if it's a file that a browser can display you can just load it as an HTML <img>.
I've also managed loading a flat image from a PSD using the psd.js library, but it's pretty slow with larger files.
If you want to specifically access thumbnail metadata in a file, that would probably take intimate knowledge of the file format, or some library that does that for you.
I had a bug in the variable and now it works with <img>
