Need Help Understanding this PHP Code

Question

i am aware of the basics like what is a function, a class, a method etc. however i am totally confused on what exactly the below code does to read the image, i read it somewhere

Answer 1

If you just want to display the image, all of the above is irrelevant. You just need to write out an HTML image tag, e.g.

echo '';

That's it.

The code that you have given takes a very long and inconvenient way to load an image for manipulation using the GD library; that's almost certainly not what you wanted to do, but if you did, then you could use imagecreatefromjpeg instead.
