Yes. When you upload your images you should receive a confirmation message on your screen, which will indicate whether your upload was a success or not uploaded correctly.
From there, it will take approximately 4-6 weeks to have your products onboarded. We will notify you via email if you have any image issues. Once your products move to "ready for processing", there is nothing further you need to do on your end.
If you have any questions regarding whether your submission was successful, submit a support ticket and we will get back to you as soon as possible!
