1) Script Title: Featured Image Zoomer
2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...uredzoomer.htm
3) Describe problem: i love FIZ but need to change the script to display the left half of an image in one magnifier and the right half in a second magnifier so that the user can visually compare them. The issue is that I need to understand the conventions and structure of the plugin better.
a) is there some documentation that goes along with this plugin?
b) If not, can anyone tell me why the author chose to prefix some variable names with $, eg, $tracker, $magnifier, etc. Does this imply that the var is private, or a jQuery object, or a HTML snippet, or, perhaps, it means nothing at all? None of these uses are inconsistent across the plugin, so I was thinking that maybe I missed something.
c) some lines end in semicolon, some don't. is there some advantage to leaving semi's off lines, besides confusing the gentle reader? semi's appear to be required, according to the MDN guide -- yet this code appears to work just fine.
