Answer to your question: No; not required; neither is it mentioned any where. All I have heard of such requirement was with US immigration only; not Canada Immigration.
Moving forward: on a second thought:
just joking; no offence meant; on the lighter side:
it might be a good idea to send a stack of photos so as to clear ALL the confusions - say things like sitting in study room studying with clock placed on table which shows the date (to prove you studied while obtaining degree), sitting on a bike next to office campus with the company board, may be some pics in working posture with laptop/computer, what about writing the actual examinations during universities?
oops, just forgot, what about paying money into the bank for Proof of funds; cant forget that!
lastly a pic with handshaking with local police (imp: both be smiling), so there are no issues with police clearance...
pardon me, if I have forgotten proving ne thing else - actually i cant think of proving pictorally the stuff like english proficiency, adaptability, etc ---- seniors can throught better thought on to this!
