Yes, it can be done that way as well, and zooming in additionally can also be done via the browser itself. Busy.org merely males these various features more obvious.
But, luckily, there are always multiple ways to do almost anything!
Thanks a lot Otto!
you are right, and of course in Busy.org it is most convenient, since you can scroll the images and there is a (+) button for zooming. This is particularly good when there is a post, like a travelogue with tons of images to peruse.
On a related matter, I wonder why Steemit redirects all links instead of opening in a new tab - even if you write the HTML code [ target="_blank" ] , it ignores it.
