View is used more often as a noun than a verb. For example:
"You should see the view from the top of the mountain - it is amazing."
It isn't wrong to use view as a verb in the way that you have done in your examples, but 'look at,' is much more common.
In the case of the paintings in the gallery, we would also be more likely to use the verb "to see," than we would "to view."
"I like to go to the gallery to see the artworks on display," for example.
