I was wondering if it's possible to have different levels of zoom which can shows differents levels of information. It's probably not really clear so the idea is that :
At normal zoom : only images
Maximum zoom : caption of the images
Minimum zoom : symbols corresponding to images (like pictogram)
And it could be really great if these layers can mix themselves with an idea of transparency. Zoom between minimum and normal would show images at 50% of opacity and their symbols at the same level of opacity.
Thanks you in advance, JJulien
