Question

Is it possible to read image as text and send it over network? Is yes, then how can we do this?

Answer 1

You could base64 encode the image to produce a (text) string.

Apache Commons Codec has a Base64 implementation that you can easily use:

import org.apache.commons.codec.binary.Base64;

// Read the byte array from file, DB, etc
byte[] imageByteArray = getImageByteArray();

String base64Image = Base64.encodeBase64String(imageByteArray);
