What is the ruling on placing pictures of scholars and shaykhs on mobile phones or computers?

There is no harm in keeping digital images of men on a computer, as long as it does not lead to their glorification. If a woman does this, she must ensure there is no suspicion or temptation, as there is a consensus that a woman is prohibited from looking at a man with lust. The preponderant opinion is that it is permissible without lust.
