I recommend ImageResizer:
Key features are:
- RESTful url-based image API (example: src="img.jpg?w=170")
- Intuitively crop, resize, rotate, flip, constrain, and encode
- Render PDFs into images
- 19 free plugins cover most common tasks
- Disk + Memory input/output caching
- 8-bit PNG/GIF & animated GIF processing
- Flexible text & image overlay support
- Image filtering suite (needs licence)
- High performance
- and more ....
For installing with Nuget:
PM> Install-Package ImageResizer.MvcWebConfig
PM> Install-Package ImageResizer.Plugins.DiskCache
PM> Install-Package ImageResizer.Plugins.PrettyGifs
