Image Browser


By default the "Insert Image" tool opens a simple dialog which allows the user to type in or paste the URL of an image and optionally specify a tooltip.

Insert Image Dialog

Since the Q3 2012 release KendoUI Editor widget supports a new way of picking an image by browsing a list of predefined files and directories. Uploading new images is also supported.

Image Browser Dialog

The image browser needs a server side implementation to retrieve and upload the files and directories.

Configuring the ImageBrowser

The image browser tool can be configured through the imagebrowser configuration option.


         imageBrowser: {
            transport: {
                read: "imagebrowser/read",
                destroy: "imagebrowser/destroy",
                create: "imagebrowser/createDirectory",
                uploadUrl: "imagebrowser/upload",
                thumbnailUrl: "imagebrowser/thumbnail"
                imageUrl: "/content/images/{0}"

The default requests and responses for the create / read / destroy / upload operations are as follows:

  • create - makes a request for the creation of a directory with the following parameters:

    { "name": "New folder name", "type": "d", "path": "foo/" }

    Does not expect a response.

  • read - sends the path parameter to specify the path which is browsed. Expects a file listing in the following format:

        { "name": "foo.png", "type": "f", "size": 73289 },
        { "name": "bar.jpg", "type": "f", "size": 15289 },

    Where name is the file or directory name, type is either "f" for file or "d" for directory, and size is the file size (optional).

  • destroy - makes a request with the following parameters

    • name - the file / directory to be deleted
    • path - the directory in which the file / directory resides
    • type - whether a file or a directory is to be deleted ("f" or "d")
    • size - optional, the file size, as provided from the read response
  • upload - makes a request to the uploadUrl. The request payload consists of the uploaded file. Expects a file object in response:

    { "name": "foo.png", "type": "f", "size": 12345 }

All of these can be changed through the imagebrowser configuration.
