adding the option of showing/hiding alt text from images

This is a great addition. This is particularly useful for a multi language app like mine where the alt text display text in languages that are not that of the user.

@mtibben really sorry for the disturbance, but any idea on when can this get a review 😀, Would really appreciate it, if you can give it a look.

@mtibben friendly ping. Would you be okay with this change?
