go to start (at the bottom left corner)
no go to programs (it should be at the top somewhere)
then to to accessories (hard to find for me atleast)
then click paint
now start a new document (file>new)
then enter the image dimensions it says to put on the cutscene editor
then put your image there
then go to file> save
then look at the scroll bar thing, and look for where it says (*.PNG Portable Network Graphics)
Click that
and look for a safe and comfy place for your file
and press save
tadaaa!
now go to cutscene editor
and everything is self explanatory there
(I get confused sometimes, dont worry!
)
