Look inside

In this liveProject, you’ll tackle an important job for Echorand Corp, a data processing company that offers image-hosting services. Echorand’s image-hosting app needs the capability to produce thumbnails for all the uploaded images, so they’ve turned to you. Your challenge is using Go to implement the thumbnail creation features. You’ll need to create a new table to store the association between the original image and their thumbnail, then set up functionality so the original image will be downloaded when users click the thumbnail.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
