forked from octoprint-filemanager (https://github.com/Salandora/OctoPrint-FileManager) to support preview images for gcode files
Install via the bundled Plugin Manager or manually using this URL:
https://github.com/shodushi/OctoPrint-GBrowser/archive/master.zip
Place image/photo of your gcode model in same folder as the gcode file with the same name and file ending ".png" e.g.: your gcode-file is named vase.gcode, put an image named vase.png as preview image into same directory.
Generating images with the same look as in screenshots section below can be done with https://github.com/shodushi/gcode2png
