Seven cows, can upload multiple pictures, then call back to app Server, and take the information of multiple pictures as parameters?

Encapsulate an upload queue by yourself, and call back to the server once all the pictures are uploaded. My approach is shown in the following figure (for reference only, if you have any questions, you can discuss them together):
