How can I make a web application that modify the images?

Question

How could I create a web page with html and php that allows users to deposit and modify image parameters (rotation, flip horizontal, scale and transparency) in a server repository. And, save both original and modified images. I'm struggling with this 🥺 .

Answer 1

You want to do it on server side and with PHP of all languages?

It would be extremely easy on the client side using a canvas though. You could then create an image blob out of it and send it to the server to save, together with the original.

If you must do it on the backend. I would recommend a more general purpose language for the backend. To have more library access.

Why not Python or JavaScript on the backend?

Answer 2

I need to do it on the server side, and as is for a proyect for my University, they specified that we can only use Html and PhP for the backend (also javascript but the largely those 2 previous languages)

Answer 3

Well. Yeah. That's all you need to do what I described. Those are all standard web technologies. You can't store reactions or any data without a database of some sort.

Answer 4

elena carrero Sorry I confused this with another question. But the response is almost the same. You can do this with JavaScript and canvas on the client side. And send the resulting image to the server to store.

All you need is JavaScript, HTML and PHP.
