thank you Opatel :-) now, it change the pic in my both symbol, but sure i'll find a way using what your answer :-)
If you want 2 symbols with different pictures you need to duplicate the symbol in the library and then swap the image in on of them.
or you can change the image in code with attr or css.
I don't find this swap option in my library ! How is it possible ?
I didn't say anything ! I found it !
Oh, great! (Mark as correct or helpful to flag the answer for others.)
I am adding the direction in case someone want to do the same thing.
Step 1 - In the symbol library panel, duplicate your symbol
Step 2 - select your image
Step 3 - click on the swap icon
Step 4 - select the new image
You can also change the image of a symbol dynamically like this
1 - your image is a DIV
2- Your image is an IMG (you can change the div to img)
(make sure you have the right path and extension for the image)
Thank you :-)
My mistake was that i used drag & alt insteed of "duplicate" :-)
Very useful. thanks
