Enjoying looking at his wife with whom he has done the marriage contract via the internet

It is permissible for a woman with whom the marriage contract
has been done to uncover part of her body or adornment to the one who did
the marriage contract with her, because she is his wife, and Allah says
(interpretation of the meaning):

“5. And those who guard their chastity (i.e. private
parts, from illegal sexual acts)

6. Except from their wives or (the slaves) that their
right hands possess, __ for then, they are free from blame;

7. But whoever seeks beyond that, then those are the
transgressors”

[al-Mu’minoon 23:5-7]. 

There is nothing wrong with that being done via the internet,
so long as the conversations or pictures are not preserved, and so long as
precautions are taken to ensure that no one has access to them or is spying
on them. 

But we do not advise anyone to do that, because it may result
in someone else seeing those images and because it may lead to extreme
provocation of desire for either party at a time when there is no legitimate
way of fulfilling it; this may push them towards masturbation which is
forbidden in sharee‘ah.
