If you have Jquery instaled on your template delete the red line.
4. Save the template.
5. The next step is to add the image to your post. When upload a large image it is resized automatic to a smaller dimension.This is perfect because the script wiil use the larger image and the resized one will be displayed on your post.
The image code you upload will look as below and you simply add class="zoom" as highlighted :
<div class="separator" style="clear: both; text-align: center;">
<a class="zoom" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh282GlTyYpkM7hyphenhyphen2yAwK4buZGzIuBE28VzCNNP7xESVPOp4Glz31F-FT49U-qXuPyELkz0hJhxLH0TBhVco9JEGZ2-Fl5LXRAmuWKIfU8hHCX9Z5i6cKB3fAqJLsKLYqQj8ke7infmWaTg/s1600/Capture2.PNG" imageanchor="1"
style="clear: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" height="210"
