Develop and Share
All Imazen software is developed on Github, with community collaboration. E-mail your GitHub username to
email@example.com, and we'll give you access to the github.com/imazen/resizer repository. We've never denied a request for access, and we happily accept and test any correctly licensed pull requests we receive. To see a list of other libraries Imazen has created, go to imazen.io.
If you're new to Git, we have instructions for installing and connecting to GitHub.
If you're not sharing code, we suggest using the NuGet packages instead to keep up-to-date, as they're updated frequently.
What should I create?
If you want to make something lots of people will use, browse the ideas forum. Or, create a module that enhances ImageResizer integration with your favorite CMS, WYSIYG editor, or media tool.
Our open plugin model makes it simple to add server-side functionality, and our rigorously standardized and backwards-compatible URL API (along with our client-side wrappers) make it easy to integrate on the front-end.
We're always quick to provide assistance to developers creating community plugins, so feel free to reach out and ask questions!
Also, check out the Redistribution and CMS Integration Guide if you're interested in redistributing ImageResizer with your product. We provide priority assistance to other open-source projects using ImageResizer.
Share your ideas and feature requests on the UserVoice forum, so others can vote on, comment about, and perhaps implement your proposals. The ImageResizer project isn't just about resizing. We're Lightroom as a web-service, but with a plugin model so things don't get bloated - and the community is free to innovate.
If your idea doesn't get enough votes to be developed by Imazen, don't despair - If you want to take a shot at implementing it, we'll help you out! We're generally willing to publish community plugins in the /Contrib folder, although you may prefer to host it on your own GitHub repostiory so we can add a link to it on this page.
A strong and diverse community is essential for the health and quality of any software library.
Many ImageResizer users monitor StackOverflow for questions tagged imageresizer, and may answer your question before we can get to it.
Please be courteous; vote good answers up, and mark them as accepted. Make sure your questions include a gist with the diagnostics page output, and you've included all relevant details and detailed error messages. It's best to register and select a username instead of posting anonymously; anonymous posts are often considered spam.
We strongly suggest reading the support page before posting, as nearly all common mistakes are explained there.
