So like, in the same way you process input from a user, process an <image>? only that I'm not having the user input an image, is just an image that I'm showing using the html <image src> tag

I don't understand the question. "Sending an image to a PHP file" makes no sense to me. The way you process input from a user is through GET or POST variables, which are part of the request sent by the browser. Since the browser won't be sending you any images, the answer to your question is "no".
The purpose of a PHP program is to produce an HTML page to send to a browser, so one usually doesn't need to process images. What exactly are you trying to do?

You need to learn how to name things if you're going to ask for help. What you want to do is to send an image from an <img> tag as part of a submit of a form. That's not possible with plain HTML and PHP since the only things that are sent in a post or get request are input fields.
If having the url address is enough for what you're trying to do, you can put the img url inside a hidden input tag and the url will sent on the form submit. But if the user doesn't chose a file it seems like you create the HTML page and already know the address, so why do you need to send it back from the browser? Why not detect when the form is received and access the img for that user?

I think this may be a starting point:
Open XML Format SDK:
Easy peasy to create any Office document from scratch. (Not so easy to parse a web page to put into that document.)
I haven't checked, but if you are lucky, maybe there even is methods in that SDK that does it all for you? I don't know.

If the image and the page url are hosted on the same domain, then you can draw the image to an offscreen canvas and get the pixel information as a png.
Canvas Save Drawing
Instead of opening the data url to save it locally, you send it to the server. You cannot do this on images with a different domain name. The canvas disables read operations once an image from another source is written to the canvas.
I wouldn't recommend that way thought, I would just send the image url to the server and let the server request the image separately. This will be more robust and probably easier to implement.
