OK.
PROBLEM SOLVED :
There was already a line calling jquery in the header of the blog creating a conflict with the version which is already included in the recent versions of wordpress.
Removing it made Shashin works as well as expected !
I also checked the console.
With Chrome and the Prettyphoto setting activated, I’ve got this error :
“Uncaught TypeError: Object [object Object] has no method ‘shashinPrettyPhoto'”
With Chrome and Fancybox : “Uncaught TypeError: Object [object Object] has no method ‘fancybox'”
(I’ve – of course – changed the parameter “How to display a full-size photo when its thumbnail is clicked” when testing with Fancy box instead of Pretty Photos before posting this comment, but no change) 🙁
