Is there a way to enlarge an image on mouse click in Google Sheets?

You can have google chrome add-on: Docs Image Zoomer

Test Here: Example

You can assign scripts to images but there's no way (that I can see) for the script to figure out which image is being clicked. Also the script can insert a new image but this one won't have a script assigned to it so we can't make it disappear on click.

I suppose you could assign a script that would open up the image using the HTML service like this:

Enlarge Picture on Click

But you would need to either make a separate function for each image, so it can load the source into the HTML, or identify which image is clicked somehow (I'll have a think but I don't think this can be done).

Edit: Script below. First image should run popUp1 and second image should run popUp2. There might be a more elegant solution for supplying the HTML with the different image URL but this works.

code.gs

function onOpen() {
  var ui = SpreadsheetApp.getUi();
  // Or DocumentApp or FormApp.
  ui.createMenu('Actions')
  .addItem('Authorise', 'Auth')
  .addToUi();
}

function Auth() {
  SpreadsheetApp.getActiveSpreadsheet();
}


function popUp1() {
  var html = HtmlService.createHtmlOutputFromFile('index1')
      .setSandboxMode(HtmlService.SandboxMode.IFRAME);
  html.setHeight(400);
  html.setWidth(600);
  SpreadsheetApp.getUi()
      .showModalDialog(html, 'Image');
}

function popUp2() {
  var html = HtmlService.createHtmlOutputFromFile('index2')
      .setSandboxMode(HtmlService.SandboxMode.IFRAME);
  html.setHeight(400);
  html.setWidth(600);
  SpreadsheetApp.getUi()
      .showModalDialog(html, 'Image');
}

<script type="text/javascript">

    google.script.host.close();
  }
