What dounttron thinks I mean: I tried dragging the adventure .PNG into the adventure editor from imgur and nothing happened.
What KrammeKat thought I mean: "I can't import pictures into Spore to use as thumbnails for adventures." or "I tried downloading the adventure from the Sporepedia using drag and drop but it didn't work."
