I am working on a purely JS/HTML page where the user can upload an image and the image is converted to canvas data and displayed. Then the user can click on a button to have alterations performed to the pixel data, changing the display.
Now, if the user wants to save the image they can right click and do a save as and they are prompted to save the image as canvas.png; I would prefer, however, to just have a button "download image" that the user can click to pop up the standard save dialogue box.
My question is how can make such a button, that pulls the canvas data into a standard image download prompt?
Here are some more details:
If you do a "view image" on the displayed image the url it goes to is like this:
data:image/png;base64,iVBORw0KGgoAA (lots more stuff)
Jacob Seidelin, has created a library that allows you to save the canvas as an image. You can find his site here!

I was just watching some street view images in this website where if you refresh everytime it loads up a new image. Then I realized a image was too beautiful and I was trying to save that image somehow, and it is when I came to know that I can't right click and same street view (Panorama) images. I thought maybe going to developer tools then network might help but it requires to be opened before I load up the page or I have to refresh the page which is disasters in this case.
I know the images loads up on browsers gets saved in the data folder of the browser. But I don't know how to retrieve them or is there any other ways I can save the image?
I'm having some issues with images on my site which I'm downloading from an image delivery service.
They're displaying perfectly fine, but the issue comes if a user tries to right click and save the image. The images seem to be leaving off the image extension. Is there any way to force the image to download as, say a jpg? I've looked at the download attribute, but I think that's only valid on links, so it's not valid in this case.
When you right-click on an image in firefox, and click on Display image, it displays it. And around it, there is a black background.
Can I put my own background image instead of the black background?
No - you're entering browser-level functionality that is beyond your control.
You wouldn't really want a user to have to resort to this anyway. Are you trying to display the image in isolation? In which case create your own 'image view' page or show it in a lightbox or something.
I'm trying to create a like button for a web gallery where underneath each picture a Facebook like button is created. I did get a like button on there at one point, but when the user clicks the like button to share it, it shows a text link to the gallery picture and not a thumbnail of the image. How do I get the like button to show a thumbnail of the gallery image when the user click the like button?
Thanks in advance.
I think I could be doing something wrong in photoshop. I'm trying to create a banner for my website.
I created a new image in photoshop, then filled the background with a color I picked #E06205
I then saved the image as a jpeg.
On my webpage, I created a div and gave it a background color
background-color:#E05206;
When I open the page in Safari and Chrome it's beautiful. Matches perfectly.
However, when I open the page in FireFox, the colors don't match. I can't figure out why that is.
By the way, this is definitely a problem with the image I created. When I compare the same image side by side, Firefox gives me the 'wrong' color
Your issue is in the color profile you are using for the image. Make sure when you save the image you use Save for Web & Devices…
