change the ajax progressbar of dotnetnukes

Is there a way to change the default ajax progressbar that is there in dotnetnukes.

Its not for changing the image but i would like to use an altogether different progressbar. The current one displays the pro开发者_开发百科gressbar at the bottom of the section. The requirement to replace it with one covering the entire section or part of it. The section has a search criteria on top and the results below. The progressbar needs to appear above the criteria so that the user will not change it while the search is going on.

That's the animated image you can replace with your own if you have one.

Agree with @DangIT, you can find the gif with name progressbar.gif in images folder in the root of dnn installation. just delete it, and place another image with the same name will do the trick for you
