Feature: Adding compression to image data before storing in database

[arnabsen1729]

Description

Using some compression before storing the images in the database. Since we are using base64 encoding for the image, the length increases by approximately 30-35% but using some kind of compression, like gzip can reduce the inflation to 2-10%. This can be a minor improvement in fetching the data from the Firebase database.

Here I have written a short script to check the compression percentage.
