We have just put a new feature in our WYSIWYG editor :
Right next to the 'insert image' button in the editor, there is now another one to 'insert image with thumbnail'.
A thumbnail is a small image that enlarges either by clicking on it or simply by 'hovering' on it with your mouse - you can choose one of these two options.
Have a look up left here : put your mouse on the winter image !
This makes a lot of sense for picture galeries for example, and I'll use it myself now for screenshots like the one in our last blogpost - with this feature of quickly enlarging images, visitors will be able to see a lot more detail which otherwise is not really identifiable.
The size of the thumbnail as well as that of the enlarged image can be set up individually, by the way.
Try it out on your website or in your own blog.
