How the Photo Booth works
The photo booth has a UI that will allow you to switch between the Drop Bears currently in your meta mask wallet.
You can click the left and right arrows to select the Drop Bear you would like and also the background you would like.
Once you have made your decision you can click update.
If at any point you no longer wish to keep the background you have selected you can simply re-connect your meta mask and select the Drop Bear in the photo booth again.
You will be able to change the background back to a flat colour or to any other image of your choice from the available backgrounds.
This will require another transaction fee.
