How to download, display blob images in Chrome? - image

I'm trying to open/download an PNG blob image of a website. I used network to find the image but it only display it as plain text.
I'm confused why the small preview image in the list shows the image. How can I download the image or get any kind of working preview?

Ok first open the webpage where the blob image is and Click inspect, then go to Network
after that refresh the page while Inspect > Network is open
Then locate the blob image in Network and click the Preview tab to see if you got the right blob
Then Rightclick on the Preview image and download the blob image
Then Locate the downloaded blob file
Now rename it with the proper Extension for the image (.png, .jpg, etc...)
Now rename it and click on yes if it asks you for confirmation
And that's it you have successfully downloaded the blob image

How chrome's "save as Image" works internally?

On a web-page, we have an image and provided a download button to download the image.
If the User downloads the image using the "download button" then image metadata information is preserved. (image original size is 1.8MB)
But the User downloads using "save as image" option (on right-click) then image metadata information is stripped completely. Even I see reduce in size as well. (Image size is 1.3 MB)
Could someone help me here to understand the chromes "save as image" functionality?

Not able to open thumb-nail image on mobile device

Website
I am using a Magento website which is not able to open the thumb-nail images on the mobile devices. I changed the css file for different resolutions inside the media block but still not able to open the images.
The images inside the red square are not opening in the mobile devices. Whenever i click on any of those images nothing happens.
The image are opening in the desktop for all size of display.
Is it happening because of wrong css code or some other reasons.
Your resolution for that size add proper image width and height in CSS.

Force image extension on right click save

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.

PHP Image Upload Resize, Watermark, Title & Copyright Info

Ive written an image upload and resize script for my website which allows users to upload images, and then the script resizes the images in 3 different sizes and adds a watermark image (my website logo) on the top.
The problem I have is, that if a user then tries to upload one of the resized photos again, it will then add the logo watermark on top of it again.
What I want is to maybe add some information to the uploaded image (i.e. author, which I could set to my website name), so that if a user uploads an image which has already been watermarked, I can put a check in my script so that I dont add the watermark logo again.
Is this possible with PHP?

Immediate Save Dialogue to Download HTML5 Canvas Image - Not Saving on Server

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!
