Question

How to upload high resolution image to folder using gd library or any method? Any help appreciated.

    mkdir("../Connectors/upload_images/$album_name/");

    $file_tmpname=$_FILES['is_albimg']['tmp_name'];

    $file_name=$_FILES['is_albimg']['name'];

    $file_nm=explode('.',$file_name);

    //print_r($file_nm); die();

    $fname2=$file_nm[0].time().".".$file_nm[1];

    $hash = hash('md5', $fname2);

    $fname = $hash.".".$file_nm[1];

                $up='../Connectors/upload_images/'.$album_name.'/'.$fname;

    //echo $up; die();

    move_uploaded_file($file_tmpname,$up) or die();

The PHP upload processing does not know anything about imges, much less about resolution. It just handles files.

If you want to create a scaled-down preview from an uploaded image (I gues that's what you want; your actual question is less than clear), get yourself familiar with GD, and create the image.

Check the docs: http://php.net/manual/en/book.image.php

Specifically, imagecopyresampled().

Please note that the code sample posted here contains grave security issues; I hope that is just an example and not production code. Check out the PHP manual on handling uploaded files here: http://www.php.net/manual/en/features.file-upload.php
