Uploading Images to Server

Last week I was working on a project and in web form we wanted to ask people to upload their images to the server, and fill the application form.

So I tried to use the FileUpload Control which is a new WebControl in ASP.NET to upload the images to the server. The point was that I wanted to restrict people to only upload images with file extension "jpg" and "gif", so because the FileUpload control by default allow all types of file format to be uploaded, I used a regular expression to extract the file extension from the file name.
Another important thing for me was the file size of the images. I just want to allow users to upload images with max size of 50Kb, so I used the Length on FileContent property of the FileUpload, and at the end of my code, I used the SaveAs method to save the file in a specific way.

Notice that while your working with web application you have to get the physical path of your web application, not the http://www.yoursite.com/ so I used the Server.MapPath(Request.ApplicationPath) to get the physical path.
