Force the browser to download image files by click

Question

Force the browser to download image files by click

I need the browser to download image files in the same way as when I click on an Excel sheet.

Is there a way to do this using only client-side programming?

<html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <script type="text/javascript" src="Scripts/jquery-1.10.2.js"> $(document).ready(function () { $("*").click(function () { $("p").hide(); }); }); </script> </head> <script type="text/javascript"> document.onclick = function (e) { e = e || window.event; var element = e.target || e.srcElement; if (element.innerHTML == "Image") { //someFunction(element.href); var name = element.nameProp; var address = element.href; saveImageAs1(element.nameProp, element.href); return false; // Prevent default action and stop event propagation } else return true; }; function saveImageAs1(name, adress) { if (confirm('you wanna save this image?')) { window.win = open(adress); //response.redirect("~/testpage.html"); setTimeout('win.document.execCommand("SaveAs")', 100); setTimeout('win.close()', 500); } } </script> <body> <form id="form1" runat="server"> <div> <p> <a href="http://localhost:55298/SaveImage/demo/Sample2.xlsx" target="_blank">Excel</a><br /> <a href="http://localhost:55298/SaveImage/demo/abc.jpg" id="abc">Image</a> </p> </div> </form> </body> </html>

How should it work when loading an Excel worksheet (what browsers do)?

Using HTML5, you can add the download attribute to your links.

<a href="/path/to/image.png" download>

The respective browsers will then request to download the image with the same name (in this example, image.png).

If you specify a value for this attribute, this will become the new file name:

<a href="/path/to/image.png" download="AwesomeImage.png">

UPDATE: As of the spring of 2018, this is not possible for the cross origin of href s . Therefore, if you want to create <a href="https://i.imgur.com/IskAzqA.jpg" download> in a domain other than imgur.com, it will not work properly. Chrome opt-out and uninstall announcement

I managed to get this working in Chrome and Firefox by adding a link to the document.

 var link = document.createElement('a'); link.href = 'images.jpg'; link.download = 'Download.jpg'; document.body.appendChild(link); link.click(); document.body.removeChild(link);

 var pom = document.createElement('a'); pom.setAttribute('href', 'data:application/octet-stream,' + encodeURIComponent(text)); pom.setAttribute('download', filename); pom.style.display = 'none'; document.body.appendChild(pom); pom.click(); document.body.removeChild(pom);

Spring 2018 update

 <a href="/path/to/image.jpg" download="FileName.jpg">

Although this is still supported, as of February 2018, Chrome has disabled this feature for downloading from various sources, which means that it will only work if the file is on the same domain name.

I found a workaround for downloading cross-domain images after a new Chrome update that turned off cross-domain loading. You can change this into a function to suit your needs. You could get a MIME type image (JPEG, PNG, GIF, etc.) with some additional research if you need to. There may be a way to do something similar with the video as well. Hope this helps someone!

This is a general solution to your problem. But there is one very important part that the file extension must match your encoding. And, of course, this parameter of the content of the downlowadImage function should be a base64 encoded line of your image.

 const clearUrl = url => url.replace(/^data:image\/\w+;base64,/, ''); const downloadImage = (name, content, type) => { var link = document.createElement('a'); link.style = 'position: fixed; left -10000px;'; link.href = `data:application/octet-stream;base64,${encodeURIComponent(content)}`; link.download = /\.\w+/.test(name) ? name : `${name}.${type}`; document.body.appendChild(link); link.click(); document.body.removeChild(link); } ['png', 'jpg', 'gif'].forEach(type => { var download = document.querySelector(`#${type}`); download.addEventListener('click', function() { var img = document.querySelector('#img'); downloadImage('myImage', clearUrl(img.src), type); }); });

Try the following:

 <a class="button" href="http://www.glamquotes.com/wp-content/uploads/2011/11/smile.jpg" download="smile.jpg">Download image</a>

You can directly download this file using the anchor tag without much code.
Copy the fragment and paste it into a text editor and try ...!

 <html> <head> </head> <body> <div> <img src="https://upload.wikimedia.org/wikipedia/commons/1/1f/SMirC-thumbsup.svg" width="200" height="200"> <a href="#" download="https://upload.wikimedia.org/wikipedia/commons/1/1f/SMirC-thumbsup.svg"> Download Image </a> </div> </body> </html>

A more modern approach using Promise and async / await:

 toDataURL(url) { return fetch(url).then((response) => { return response.blob(); }).then(blob => { return URL.createObjectURL(blob); }); }

then

 async download() { const a = document.createElement("a"); a.href = await toDataURL("https://cdn1.iconfinder.com/data/icons/ninja-things-1/1772/ninja-simple-512.png"); a.download = "myImage.png"; document.body.appendChild(a); a.click(); document.body.removeChild(a); }

Poisonous Whisper · Answer 10 · 2019-06-19 12:53

What about using the .click () function and tag?

(Compressed version)

 <a id="downloadtag" href="examplefolder/testfile.txt" hidden download></a> <button onclick="document.getElementById('downloadtag').click()">Download</button>

Now you can run it using JS. It also does not open, like other examples, graphic and text files!

(js function version)

 function download(){ document.getElementById('downloadtag').click(); }

 <!-- HTML --> <button onclick="download()">Download</button> <a id="downloadtag" href="coolimages/awsome.png" hidden download></a>

I found that

<a href="link/to/My_Image_File.jpeg" download>Download Image File</a>

didn't work for me. I'm not sure why.

I found that you can enable the ?download=true Download ?download=true option at the end of your link to force download. I think I noticed that this method is used by Google Drive.

In your link, include ?download=true at the end of your href.

You can also use this technique to set the file name at the same time.

In your link, include ?download=true&filename=My_Image_File.jpeg at the end of your href.

António Regadas · Answer 13 · 2013-07-08 13:32

You do not need to write js for this, just use:

 <a href="path_to/image.jpg" alt="something">Download image</a>

And the browser itself will automatically download the image.

If for some reason it does not work, add a download attribute. With this attribute you can set a name for the uploaded file:

 <a href="path_to/image.jpg" download="myImage">Download image</a>

Force the browser to download image files by click
