Feature Request - Display arbitrary images

[lnafziger]

The lambda tag is great for displaying a particular image which you have in advance, however I would love to see the ability to support arbitrarily named images that aren't available at compile time (ie they have been downloaded or created by the user).

Support for the tag would probably be the best way, but another, more generic option would be to create another lambda function which takes an argument (so that we could create a lambda called "img" and pass the filename to the block).

This looks like a great component, thank you for sharing!!!
