You could swap the image with:
rather you need to target the images into the symbol but the css code is right.
You could also have several images in the symbol and use hide() and show() to choose the image you want - that is if the images are rather small.
Thank's a lot man,
this works for me ;-)
I also found another solution in this post.
I just have to export and then import the symbol again.
Thank you so much!
Yes, that was a great post! I hope Adobe hired her to write their doc - Ha!
