ImgPen image editor is built into Flmngr file manager and in most of cases you do not need to call it manually due to its button is already inside the file manager select files dialog - user will open the image editor from there, edit an image and save it back to the server.

But when you need to call image editor outside of file manager context, you can do it using Flmngr API.

With such API and its Flmngr.editAndUpload({params}) method you can call image editor with image from your storage or outside of it, and then save the result image into your storage. The parameter url and the callback onSave(urlNew) will help you with this task.

If you do not need to save edited image in the storage at the same moment, there are atomic Flmngr.edit({params}) and Flmngr.upload({params}) methods, and there is a separate sample of their usage.

This sample uses Flmngr.getNoCacheUrl() method to add ?no-cache=time suffix to the new URL because if user saved a new image by rewriting the existing one, browser will not refresh (reload) an image already existed on the page until you refresh whole the page - this is a feature of all browsers. Fortunately, Flmngr API has the method to bypass this pitfall.
