Taking pictures on scratch?! First press space and then please sit still for 5-60 seconds... (bad times i know...) (You can finally take pictures after one another.) To export your picture please open the project and export the list itself. To import do the opposite. Press space to take a picture.
Turbowarp might be better: https://turbowarp.org/791853075 (Or use turbo mode. Shift+Green flag AFTER LOADING) Notes: (For optimal speed, please sit with a background without too many color.) (The resolution goes up to 480, but 240 is recommended as anything above is slower.)
