Hi Santosh,
I am not agree with Leadvue's response.
As currently Syamntec DLP does not have OCR functionlity to detect sensetive information from images/jpeg etc. I guess they are working on it. As per Leadvue you can not block all Images to removable media and so on. there are few alternate option which can help you to achive above requirement.
I would suggest, identfy the jpeg (scan) files or image files that are being availble in you network/machine theough discover and other method,try to search through file name,folder etc smart serch methods and use IDM techlogy to create profile and detect the sensetive information transferred through image files.
