TinyMCE uploads edited images with the image uploader. This complements TinyMCE’s image editing functionality.

Local images that are added through other means are also uploaded using this function, such as images added by drag and drop when using the paste_data_images configuration property, or using the Tiny PowerPaste plugin.

TinyMCE automatically updates the <img> src attribute with the new path to the remote image.

Local images are uploaded to TinyMCE using the editor.uploadImages() function. This functionality makes it possible for users to save their content before all images have completed uploading. If this occurs and no server path to the remote image is available, the images are saved as Base64.
