First, some questions.
- Are you using the URL API?
- Are you using the managed or COM API?
If you answered "no" to #1 and "yes" to #2, see our non-web installation guide. Console, WPF, WCF, WinForms, and Classic ASP users sometimes choose to only use the Managed API.
If you answered "yes" to #1, and "no" to #2, you might consider using ImageResizer as a standalone image server. PHP, Ruby, and Python users might consider this, as well as users with dozens of terabytes of images.
Note: If you want to modify Web.config yourself, substitute
ImageResizer.MvcWebConfig below. MvcWebConfig will only add - never delete - elements in Web.config.
via the NuGet Package Manager Console (option 1)
Open the nuget console from Visual Studio via
Library Package Manager >
Package Manager Console.
PM> Install-Package ImageResizer.MvcWebConfig PM> Install-Package ImageResizer.Plugins.DiskCache PM> Install-Package ImageResizer.Plugins.PrettyGifs PM> Install-Package ImageResizer.Plugins.SimpleFilters
via the NuGet GUI (Visual Studio) (option 2)
- Right-click on your project and click "Manage NuGet Packages".
- Select "NuGet Official Package Source"
- Search for "Imazen", using the search bar at the top right
- Select "ImageResizer Web.config Installation (with MVC support)" and choose Install
- Repeat for each desired plugin. All plugins can be safely combined
- Check the documentation for each plugin to see if additional steps are required to activate the plugin. Only some NuGet packages auto-activate the included plugin(s).

Manual Installation (option 3)
Download and unzip the package. Add
ImageResizer.Plugins.DiskCache.dll, and any other plugin dlls you wish to use to the
/binfolder of the website. If you're using Visual Studio, right click your project and choose "Add Reference" for each of these files instead.
Modify or create the /Web.Config file for your site. Make sure all these elements are added correctly (You may wish to make a backup of Web.config first).
<?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="resizer" type="ImageResizer.ResizerSection,ImageResizer" requirePermission="false" /> </configSections> <resizer> <!-- Unless you (a) use Integrated mode, or (b) map all requests to ASP.NET, you'll need to add .ashx to your image URLs: image.jpg.ashx?width=200&height=20 --> <pipeline fakeExtensions=".ashx" /> <plugins> <add name="MvcRoutingShim" /> <add name="DiskCache" /> <!-- <add name="PrettyGifs" /> --> <!-- <add name="SimpleFilters" /> --> <!-- <add name="S3Reader" /> --> </plugins> </resizer> <system.web> <httpModules> <!-- This is for IIS5, IIS6, and IIS7 Classic, and Cassini/VS Web Server--> <add name="ImageResizingModule" type="ImageResizer.InterceptModule"/> </httpModules> </system.web> <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <modules> <!-- This is for IIS7+ Integrated mode --> <add name="ImageResizingModule" type="ImageResizer.InterceptModule"/> </modules> </system.webServer> </configuration>
Start your web site, then visit /resizer.debug.ashx to verify you've done everything correctly. If you ever encounter issues, simply revisit that page to access the self-diagnostics. If you need help, just ask!

Review the Best Practices Guide and our license options.
Get an ImageResizer license, which includes disk caching and dozens of other valuable plugins.
Take a look at client-side components like Slimmage.js, which can make responsive images painless. There are many third-party libraries that can make integration easier.
