What does the action do exactly? First of all the model is checked for validity. Now this looks pretty complicated in the beginning. Please try again using only correct images!") ModelState.AddModelError(errorField, " Your upload did not seem valid. Var img = CreateImage(original, model.X, model.Y, model.Width, model.Height) Var fn = Server.MapPath( " ~/Content/img/" + name + ". Original = Bitmap.FromStream() as Bitmap Name = Path.GetFileNameWithoutExtension() Original = GetImageFromUrl(model.Flickr) Public ActionResult UploadImage(UploadImageModel model) Let's start with the model that will actually be transferred from the client to the server: In general a webpage will have something like this - but for this mission those two things are not required. For simplification we just remove everything that has something to do with a database or user accounts.
We start with the "Internet Application" template from the ASP.NET MVC 3 package. Ready? So let's actually build this fancy image uploader! Implementation We do want to stay focused on our mission here. The JavaScript will then modify the page for the second (usually much larger) type of users: those with JavaScript enabled. Overall any page that takes non-JavaScript browsers into account must first handle those users.

The code would need to include funny things like previously hidden states that will be made visible again by JavaScript and vice versa. Therefore a huge part of this article would be dispensable. The whole thing of preprocessing an image before the image is actually uploaded is obsolete without JavaScript. We will not implement any fallback code, even though a non-JavaScript solution could be implemented as well. Some of the form's elements will be hidden and will be changed by the jQuery plug-in which helps us do the cropping. We need a checkbox to indicate the currently selected method. Here we will offer the three possibilities (file upload, URL, Flickr). Those events affect mainly the inside the page. Then our JavaScript code will handle the client-side events on the generated website. So ASP.NET MVC has the responsibility to generate the page (which does not need much generation since it is mostly static). The basic idea of this whole process is displayed below. In order to preview images from the local file system we will use the FileAPI, which is available in all current browsers. The plug-in will enable us to do (instant) cropping from the client's web browser. The client side will heavily use jQuery and a plugin called ImageAreaSelect. We will build everything with ASP.NET MVC 3 on the server-side. From Flickr (per image search, selecting an image from the list of results). From another URL (resource from the internet). From the local file system (standard file upload). Our image uploader will have (about) the same options as the one that is used by Google for uploading images in the contacts web application. Additionally our image uploader should be able to perform an easy crop job. However, we want to build an image uploader that can handle more than just plain file uploads. We do not want to build a very rich editor in this article, A common problem is the lack of image editing options. 
The requirement could exist due to a CMS background or due to user generatedĬontent like profiles, posts, and various other usages. Uploading an image to a website is a task that is required in nearly every website.
