Server-side verification of PNG files #5
Description
In the same way that #3 is a verification for PDFs, provide some verification for the upload of PNG files. It is important that you find a solution which MINIMIZES the size of the deployment package that Chalice will create. Many image processing libraries exist which have large dependency trees and tons of features. This makes our deployment bloated and often go over the 50MB limit. Please make sure your verification of PNG is done in the smallest overhead of deployment size possible.
We are interested in hearing a proposal about using Lambda Layers if you think this is a viable option. However, DO NOT implement anything with layers prior to discussing with us.
