I am trying to use the Nivo JQuery Slider (http://nivo.dev7studios.com/) and a Scrollable Gallery (http://flowplayer.org/tools/demos/scrollable/index.html).
Now I have
use this solution if you cannot use a single jQuery file for both the plugins:
To use jQuery 1.4.2, put the code using it in a SEF (Self Executing Function) like this:
(function($){
//code using jQuery 1.4.2
//here the $variable will be the jQuery object of 1.4.2
})(jQuery_1_4_2)
For jQuery 1.2.5, you can use $ variable directly.
UPDATE: Based on your comment, following is the way to use it.
If you want to use jQuery 1.4.2, use jQuery_1_4_2 object
For example: jQuery_1_4_2("#abc").slider(options)
If you want to use jQuery 1.2.5 use $ or jQuery object
For example: $("#abc").scrollable(options)
