How to let user upload image in one page, and then display it in another page? User can change the image and it'll be changed also in the other page. Also, I'm talking about using php / js / jquery / mysqli anything that's most efficient. (I'm just a beginner in this field so it'll be appreciated if you use some simple language :))
Edit: Yes I said that I'm a beginner, but that doesn't mean I don't know a thing about coding. Also, I saw a few solutions from youtube & other stackoverflows questions, but all of them is about either uploading and displaying in the same page or not being able to change the image.
