Fixes saving your artwork.

If you attached a photo and saving failed, or it saved but never turned up in your gallery, that was this. Both are fixed, and your prompts and streaks are untouched.

Pieces that failed to save didn't make it through, so please re-add those. The original photos are still in your camera roll.
