GDI and web forms

Since Images are a separate Request from the client to the server, you have to build any graphics for web forms into its own ASPX page. The trick is the same as it was for old-world ASP, you write to the Response stream using the Image.Save(Request.OutputStream, ImageFormat). This is awesome for simple things like getting images from dbs and making bargraphs on the fly. I wrote a cool imagegallery webcontrol that resamples and resizes large images, then streams them to the client, and they are listed in a datagrid--it takes params for file, width, & height. I also put output caching on the page so that the images don't have to get rebuilt on every hit. It makes cleaner thumbnails than the GetThumbnail method since it changes the pixeldepth. My Image Gallery Well, anyways, those are some cool examples of GDI for the web.
