Rich Text Editor allows to insert images from online sources as well as local computer where you want to insert the image in your content. For inserting the image to the Rich Text Editor, the following list of options have been provided in the insertImageSettings

Options	Description
allowedTypes	Specifies the extensions of the image types allowed to insert on bowering and passing the extensions with comma separators. For example, pass allowedTypes as .jpg and .png.
display	Sets the default display for an image when it is inserted in to the Rich Text Editor. Possible options are: ‘inline’ and ‘break’.
width	Sets the default width of the image when it is inserted in the Rich Text Editor.
height	Sets the default height of the image when it is inserted in the Rich Text Editor.
saveUrl	Provides URL to map the action result method to save the image.
path	Specifies the location to store the image.

Upload options

Through the browse option in the Image dialog, select the image from the local machine and insert into the Rich Text Editor content.

If the path field is not specified in the insertImageSettings, the image will be transferred into base 64 and blob url for the image will be created and the generated url will be set to the src property of img tag.

<img src="blob:http://ej2.syncfusion.com/3ab56a6e-ec0d-490f-85a5-f0aeb0ad8879" >

If you want to insert a lot of tiny images in the editor and don’t want a specific physical location for saving images, you can opt to save format as Base64.

In the following sample, the image has been loaded from the local machine and it will be saved in the given location.

Drag and drop with specific extension images

You can allow the specific images alone to be uploaded using the the allowedExtentions property. The extension can be represented as collection by comma separators. By default, the Rich Text Editor allows the JPG, JPEG, and PNG formats. You can configure this formats as follows.

    insertImageSettings: {
      allowedTypes: ['.jpg']
    }

Prevent drag and drop action

You can prevent drag-and-drop action by setting the actionBegin argument cancel value to true. The following code shows how to prevent the drag-and-drop.

    actionBegin: function (args: any): void {
        if(args.type === 'drop' || args.tpe === 'dragstart') {
            args.cancel =true;
        }
    }
