uploading image

[pranshu82202]

Well i have a php script which i use to upload jpg or gif  images only...

 

I want that whenever user uploads an image of any resolution my script transforms it to 100*100 resolution..

 

What should i do...

 

Here is my PHP Script...

 

$_FILES["file"]["name"]=$_SESSION['id'].".jpg";
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 20000000))
  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    }
  else
    {
/*
    echo "Upload: " . $_FILES["file"]["name"] . "<br />";
    echo "Type: " . $_FILES["file"]["type"] . "<br />";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
*/
    if (file_exists("upload/" . $_FILES["file"]["name"]))
      {
      echo " You have already uploaded your profile pic...";
      }
    else
      {


      move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . $_FILES["file"]["name"]);
//rename("/upload/" . $_FILES["file"]["name"], "/upload/" . $_SESSION['id'] );
$_SESSION['result']="PROFILE SETUP SUCCESSFULL";
header('location:members.php');
      }
    }
  }
else
  {
  echo "Invalid file";
  }
}

What should i do...

1. Go to http://www.google.com.

2. Enter search terms such as "php thumbnail image" (which is what you want to do, after all)

3. Search

4. ???

5. Profit!

You need to look at the GD image functions:

imagecreatefromjpeg or imagecreatefromgif

imagecopyresampled

imagejpeg or imagegif

A class that is a few years old, but handles this kind of stuff with ease (especially to the user), is called SimpleImage.  I have used it in the past, and have recommended it before.  I think it might could help you do what you are trying to do.
