Thumbnails as a file

[SEALBG]

Hello guys! Can you implement the option to add the thumbnails to be like a file. Not sure if this will be possible the picture to be generated and then to be made as gif, png or jpg and then Mansail to visualize it... Now all the code is added directly inside the gcode and this add lot of lines in the beginning of the this file. As we know Klipper reads this file line by line and have limits how many lines can read in one pass. And I think this will be a cool function and for sure such option is available in other slicers. Why this function could be useful too: In some cases it may be useful to read information that is available inside the file itself and this information to be used in special cases by written code to be executed in Klipper. For example, to read the type of material that will be used before the actual printing and this material to be used for example as a parameter in the code afterwards. In the gcode file the type of material is added and is available as a comment, but it is very far down in lines. There is a possibility to be moved to the beginning of the file in such cases with the Machine G-code...
