What is digital image shares in visual cryptography?

Conventional visual secret sharing (VSS) schemes hide secret images in shares that are either printed on transparencies or are encoded and stored in a digital form.What does the word share mean here?

Anushka - check the Wikipedia article on Visual Cryptography where it describes the shares as components of the original image so that any one share (on its own) does not reveal anything about the original (secret) image. Only if you have all of the shares can you determine the secret image.

jayasri - please delete your post (since it isn't an answer to this question) and re-post as a question. Provide as much detail as possible (for example, are you splitting your image into 8x8 blocks?).
