Converting Media(jpg, mp4...) into Base64 data, insert into database, and displaying onto html page

//Python Part//
import base64, sqlite3

with open(filename, 'rb') as fout:
base64_data = base64.b64encode(blobData)
return base64_data

statement = 'INSERT INTO mytable(pic BLOB NOT NULL) VALUES(?)'
with conn:

//HTML Part//
img src="{{link}}"

What it really looks like:
img src="data:image/png;base64,343,3424,34234,,2342,,345,434.."
