Image upload in ASP.net

Hi

just simple as it looks .. 

Use Fileupload.postedfile.ContentType=="[required format u need]";

Then after we have to use

AJAX "update progress bar " control & place label on to it & name it . when file getting uploaded the required text i.e u needed 'file is uploading ' will be displayed , once uploading is done the text gets disappears & page will redirect to page you required with required text or else you can make use of visible option on top of label on same page:)
