Thanks for the image, BUT... What you are showing was my take-away (and apparently Paul's, too) from your verbal description. The Questions that I asked pertained to dimensions and aspect ratio, which you have still not addressed at all. The width labels "desktop", "tablet" and "mobile" do not convey the range of widths that you are using. Sure, we can probably come close, but you can certainly be specific, too.
About the image: what are its native dimensions and what does it look like? Specifically, should it's aspect ratio (shape) be respected like a portrait or identifiable structure OR is the aspect ratio not important such as a random pattern might be which could be stretched in any direction and still look "normal" to a visitor? In case the aspect ratio should be respected, can the top and bottom ends or left and right edges be cropped out of the picture as the width of the viewport changes?
Do you see that your "drawing" shows the size and shape of the image changing from square to horizontal. I would like to know how much it can be allowed to change, if it can at all. I noticed that your "image" shows the text in the middle of the rectangle (space above and below it) on the Tablet and mobile views. That is why I keep asking about the aspect ratio of the image and how much can be cropped?
What is the actual width of the desktop web page? I trust that you remember that the width of a browser window is not tied to the width of a montor screen.
How much text content is involved? Your drawing shows the size of the text becoming smaller at tabet and mobile widths. Is that to be the case? If so, it needs to be so stated in your requirements so the desktop text size is larger than the default and therefore can be reduced in smaller devices and by how much.
What kind of guidelines or code base or framework are you using that defines the breakpoints? Can the breakpoints change or are they written into the framework and inconvenient to change?
Can you post a link to your test web site so we can evaluate what you are doing? Can you attach the image to your next post?
Paul has already offered two very impressive guesses that don't quite meet your (undefined) expectations. I'll be glad to help you finish this issue, but I want more usable information with which to do it.
If you are just daydreaming, say so, because what you are showing in your image of images still does not strike me as realistic.
