Ender 3v2 Creality Print Thumbnail

Hi guys.
I am using Ender 3v2 and i want to see thumbnail on screen with creality print’s gcode. I dont want use cura or others slicer because print time is so different

Having the same problem and looking for a solution.

I look into the files and I am sure that the problem is related to the dimensions and sizes of the jpeg thumbnail from Creality Print.The gcode file from Creality Print uses a 300x300 px file which is too big. it needs to be 230x180. I am not sure about the file size itself but it can’t be too large either.

I tried 96x96 px but it didnt work. I created gcode with cura and ı copied cura’s thumbnail code to creality print’s gcode. It worked.
