On Lexica.art you can mix the introduction of an image (for registered users) and its description!
But the result is only returned by pack of 4 at each generation and not very fast! (better than nothing)
Clicking on a "generated" image will only return an image related to the entered image but not its definition!
Here a picture of Gaugan as a start to give it an Art Nouveau style!
In fact to be sure to have an Art Nouveau waterfall...you have to press the "Generate" button and not "Search".
