by Jacob Gilley As a regular to ASP 101, I feel it neccesary to give a little back to the site that keeps me on top of things in the world of ASP. And so, I give you the FileUploader ASP Library. In a nutshell, the FilerUploader library is simply a single ASP include that provides an object-oriented approach to getting files from Internet clients.

ASP.NET and the .NET framework make the task of generating images on the fly very easy. With classic ASP, developers were forced to use third-party components like ASPImage and ASPPicture for dynamic image manipulation. Fortunately, with ASP.NET, those days are over. Various image manipulation capabilities are now built directly into the .NET framework classes. The .NET Framework offers several classes for image generation and manipulation. ASP.NET developers can use these classes to…
