ImageGen

2020 - ImageGen has been retired.

Don’t waste valuable time resizing images in Photoshop. ImageGen is an easy-to-use application for your Umbraco (or any .NET 2.0+) website that automates the process for you.

Do you need to create photo or lightbox galleries, screenshot flip books, staff profile or directory pages? Would you like to automatically create graphical text from any font on your server for headlines or menus? Do you need to protect your site’s images with a watermark?

ImageGen can create text graphics as well as overlay text on images. And ImageGen can automatically protect and brand your images with watermarks and corporate logos.

With more than 30 options, ImageGen can create hundreds of thousands of variations to meet virtually any need. ImageGen is easy to install and use on your website. ImageGen creates extremely high-quality images quickly. And ImageGen’s advanced caching means images are served immediately for fast and responsive websites.
