Cover questions

Hi All and Team Zazzle,

Is anyone able to clarify:

1 - Once the feature that puts designs that are the same but with different colours is back working, will the products need to have the same cover?

2 - My mockups are with a very large size. Do I need to resize it from web (e.g. less than 300Kb).

Thank you in advance for your help!

As far as size goes.. at the recommended 1480x1480 my covers tend to be around 1-2 mb when saved as jpgs
