I have a feature request. I use your plugin for Widget and want to use for shortcode too in next time.
Now after every update my link widget is broken, because you added after the images a break tag. I use only small pictures like a favicon and this should be in one row. I think it looks better. So if you add a big picture it is better to have a break?
My idea is to add something else, that you choose dynamically if you want the break or not. At this moment i go to your code and delete the break tag and replace it with a blank after every update.
