Hey I am Valentinas
Toady I wanted to ask is there a plugin or add-on to make every stroke from gimp (after auto save on same file, opened from same folder and both programs gimp and blender having it in read/write I/O mode) visibal on image after auto saving it on hard drive then reopening in blender and applied to all unwrapped materials with same image. Blender probably should checking if file size still the same? 
Okay I have tryed to find one but on my parent controlled laptop so make some search to help for all community and me.
