Mozilla Dev Derby: Drag&Drop
This is a (very) short story about someone named Pete. And Pete needs a little bit of your help.
Of course I hope you figure out yourself what to do. But maybe it is not always obvious enough. So here is a little walkthrough:
0: Start screen.
1: Drag'n'Drop a file (size matters) on that green lump of slime.
2: See the note in the slimy remains? Drag'n'Drop it on Pete.
3: Drag'n'Drop an image file on the checkered part of the shirt.
