This is to ask if there is and if there should be an official position of math.SE about the inclusion, as images, of pages and pages of printed documents in questions. For a recent example of the practice I have in mind, see this question.
Such a modus operandi seems to me to go against the principle that some work should be put into the question. Furthermore, those of us who teach know it is often helpful to ask the student to state the definition and to state the question to be solved in her/his own words (this remark is due to Willie Wong in a comment to this post).
To me, the inclusion of printed-pages-of text-converted-to-images in questions is mainly a sign of laziness. I feel the practice appeared recently on math.SE and is spreading now, and I would like it to be specifically discouraged.
