image size and imagemapper

And for the ImageMapper issue? As you can see here
my “image maps areas” fits in their respective rectangles…but when i publish in the webpage they don’t. Could you help me?

Sorry it’s just my first experience with WordPress and with coding in general 😀

the same page http://www.fibrosipolmonare.com/algoritmo/
you can see a lighting rectangle when you pass with your mouse over the right side of the top part of the image, that’s a link for another page. In the draft page it fits with the first red rectangle of the image (“La TC ad alta risoluzione è normale…”), but when I publish it it don’t.
