Quill - Add Image URL instead of uploading it

Question

I'm not a pro in JS and I'm using Quill Rich Text Editor for one of our projects. It's working well, but when I use getContents() method to get its contents (with Delta format), it shows the images, like the following:

{
  "insert": {
    "image": "data:image/png;base64,iVBORw0KGgoAA...=="
  }
}, ...

I want to give the editor a URL for the images when I add them, instead of uploading one. I mean, I want it to show the URL input box when I add images, instead of opening a file dialog for selecting an image. Like what I do when I add videos:

How can I achieve this? Should I edit quill.js codes?

Even though I am late here I post the answer as it might help someone visiting here.

You can define a custom handler for the image option. Something like this would do.

//add the toolbar options
var myToolbar= [
    ['bold', 'italic', 'underline', 'strike'],       
    ['blockquote', 'code-block'],

    [{ 'color': [] }, { 'background': [] }],         
    [{ 'font': [] }],
    [{ 'align': [] }],

    ['clean'],                                        
    ['image'] //add image here
];


var quill = new Quill('#quill-container', {
    theme: 'snow',
    modules: {
        toolbar: {
            container: myToolbar,
            handlers: {
                image: imageHandler
            }
        }
    },
});


function imageHandler() {
    var range = this.quill.getSelection();
    var value = prompt('please copy paste the image url here.');
    if(value){
        this.quill.insertEmbed(range.index, 'image', value, Quill.sources.USER);
    }
}

For Anyone looking to take the url from the quill tooltip not from the prompt.

Custom URL Image Handler for React based on this comment for biz-quill

function imageHandler() {
  const tooltip = this.quill.theme.tooltip;
  const originalSave = tooltip.save;
  const originalHide = tooltip.hide;

  tooltip.save = function () {
    const range = this.quill.getSelection(true);
    const value = this.textbox.value;
    if (value) {
      this.quill.insertEmbed(range.index, 'image', value, 'user');
    }
  };
  // Called on hide and save.
  tooltip.hide = function () {
    tooltip.save = originalSave;
    tooltip.hide = originalHide;
    tooltip.hide();
  };
  tooltip.edit('image');
  tooltip.textbox.placeholder = 'Embed URL';
}

And In your Quill Modules add this like:

export const modules = {
  toolbar: {
    container: '#toolbar',
    handlers: {
      undo: undoChange,
      redo: redoChange,
      imageHandler: imageHandler, //Add it here
    },
  },
  history: {
    delay: 500,
    maxStack: 100,
    userOnly: true,
  },
};

You can create a custom button icon from svg like this:

const CustomImageFromLink = () => (
  <svg class="svg-icon" viewBox="0 0 20 20">
    <path d="M18.555,15.354V4.592c0-0.248-0.202-0.451-0.45-0.451H1.888c-0.248,0-0.451,0.203-0.451,0.451v10.808c0,0.559,0.751,0.451,0.451,0.451h16.217h0.005C18.793,15.851,18.478,14.814,18.555,15.354 M2.8,14.949l4.944-6.464l4.144,5.419c0.003,0.003,0.003,0.003,0.003,0.005l0.797,1.04H2.8z M13.822,14.949l-1.006-1.317l1.689-2.218l2.688,3.535H13.822z M17.654,14.064l-2.791-3.666c-0.181-0.237-0.535-0.237-0.716,0l-1.899,2.493l-4.146-5.42c-0.18-0.237-0.536-0.237-0.716,0l-5.047,6.598V5.042h15.316V14.064z M12.474,6.393c-0.869,0-1.577,0.707-1.577,1.576s0.708,1.576,1.577,1.576s1.577-0.707,1.577-1.576S13.343,6.393,12.474,6.393 M12.474,8.645c-0.371,0-0.676-0.304-0.676-0.676s0.305-0.676,0.676-0.676c0.372,0,0.676,0.304,0.676,0.676S12.846,8.645,12.474,8.645"></path>
  </svg>
);

And then just add it to your toolbar like:

  <button className="ql-imageHandler"> //class is ql-yourHandlerName
    <CustomImageFromLink /> //Your Icon Component
  </button>
