Image Upload and Cropping with PHP and Jquery

Image cropping is the most important and required part in social media projects. In this post my friend Arun Kumar Shekar had implemented image cropping functionalities such as upload image file into physical location, cropping image using jquery and resizing image into small resolution. Hope you like this thanks!

  15. very good script.
    I want to make 3 different height & width thumbnails and also want to show 3 previews.
    How this can be possible.

  16. thanks for a script….i want the default selection on image…like when i upload an image, the script will automatically show a selection area on image…any idea how to do that

    ReplyDelete
  17. thanks for the script it's useful for me..

    ReplyDelete
  18. I wrote a script similar to this some time ago and found that if you don't limit the maximum number of pixels an image can be you'll be sorry. That or get a high memory server and really bump your php memory limit. You can upload a file that's small in file size but it's the pixel count that will get you when you least suspect it.

  28. Hi Arun and Srinivas.

    this is nice and superb tutorial. I have successfully implemented this crop option for my new site. and its working perfectly.. i really like it.

    when i tested with different images with high and low resolutions it save a wrong selection then i figure out.. its because, there is max-width has given on the image so the images. should be resized to that much or increase max width. then it works perfectly.. finally i have integrated. PhpTHumb v.5 to resize to 900px width if users are uploading higher images. problem solves. its fantastic..

    thank you.

  32. hi
    Great work, it help me very much

    ReplyDelete
  33. The code works if the original image has 500 pixels width. The problem comes when the original image is bigger or smaller than 500 because the coords of selection and the selection area are calculated under an image of 500 pixels width applied to a bigger or smaller image, thus the thumbnail fails to get the right area of selection.

    Also this is pointless, because it will always return 100:

    $t_width = 100; // Maximum thumbnail width
    $t_height = 100; // Maximum thumbnail height
    $ratio = ($t_width/$w);
    $nw = ceil($w * $ratio);
    $nh = ceil($h * $ratio);

    if $ratio = 100 / $w then $w = (100/$ratio) thus:

    $nw = (100/$ratio) * $ratio --> $nw = 100. I dont see the point of this.

    Also, i modified the code from ajax_iamge.php so it gets the right proportion and area of the image like this:

    list($ancho, $alto) = getimagesize($path.$img);
    $ratio = $ancho / 500;
    $x1 = ceil($x1 * $ratio);
    $y1 = ceil($y1 * $ratio);
    $w = ceil($w * $ratio);
    $h = ceil($h * $ratio);
    $nw = 100;
    $nh = 100;
    $nimg = imagecreatetruecolor($nw,$nh);
    $im_src = imagecreatefromjpeg($path.$img);
    $new_name = "small".$img;
    imagecopyresampled($nimg,$im_src,0,0,$x1,$y1,$nw,$nh,$w,$h);

    and the rest....

    The ratio is 500, because in the drag the image part it is set to 500:

    style='max-width:500px'

    hope it helps

  35. When I crop an image that is not jpg it doesn't save the resized image, any ideas why this could be happening? Thanks!

    ReplyDelete
  36. About the extensions:
    Instead of just having:
    $im_src = imagecreatefromjpeg($path.$img);

    You need to add have something like this:
    switch($extension){
    case 'bmp': $im_src = imagecreatefromwbmp($path.$img); break;
    case 'gif': $im_src = imagecreatefromgif($path.$img); break;
    case 'jpg': $im_src = imagecreatefromjpeg($path.$img); break;
    case 'png': $im_src = imagecreatefrompng($path.$img); break;
    default : return "Unsupported picture type!";
    }

    Of curse, you will need to send the extension parameter thrugh the URL, something like this:
    url:"ajax_image.php?t=ajax&img="+$("#image_name").val()+"&extension="+extFile+"&w="+thumb_width+"&h="+thumb_height+"&x1="+x_axis+"&y1="+y_axis,

  65. Hi,

    I am using jquery 1.2.6 is your crop functionality is working on this version.

    ReplyDelete
  66. Using Paris Bello's fix above with the following changes will resolve the issue of the thumbnail not being the correct selected area for images smaller than the set max-width.

    1. Obtain image height
    The code is set to restrict the max-width:500px so to account for images smaller than 500px wide you must obtain the image's width. Inside the getSizes() function add a variable set to the images width:

    var img_width = $('img#photo').width();

    Then pass this variable as a parameter in the ajax call:

    url:"cropimages/ajax_image.php?t=ajax&img="+$("#image_name").val()+"&w="+thumb_width+"&h="+thumb_height+"&x1="+x_axis+"&y1="+y_axis+"&ow="+img_width

    Now in the ajax_image.php code, change the ratio variable to use the image width you've now passed:

    $ratio = $ancho / $ow;

    Hope this helps and save you some time.

    ReplyDelete
  67. I've also resolved the issue with uploading files with any periods in the file name.

    For example, if a image is named 1234.567.jpg the code will not grab the extension properly through the explode method currently being used. I changed the code to instead grab the extension using pathinfo().

    $txt = explode(".", $name);
    $ext = pathinfo($name, PATHINFO_EXTENSION);
    if(in_array($ext,$valid_formats) && $size<(1024*1024)){
    $actual_image_name = $userid.time().substr($txt[0], 5).".".$ext;

  74. for those who are having a problem regarding in preview just erase the max-width in the line 70 and it will works fine :)

    ReplyDelete
  75. Nice! Thank you for this very helpful all of the ideas :)

    ReplyDelete
  76. Anyone having problems with generating a thumbnail for a very small image? Hope this fill help:

    if ($ancho <= 500 )
    $ratio = $ancho / 500;

    if ($ancho <= 400 )
    $ratio = $ancho / 400;

    if ($ancho < 300 )
    $ratio = $ancho / 300;

    if ($ancho <= 200 )
    $ratio = $ancho / 200;

    if ($ancho >= 100 )
    $ratio = $ancho / 150;

    By the way using Paris Bello fix.

    ReplyDelete
  77. ****UPDATE*****
    Found a better solution for the aspect ratio not showing what it selects, use this instead

    if ($ancho > 500 )
    $ratio = $ancho / 500;
    else
    $ratio = $_POST['w'] / $_POST['h'];


    Just divide the posted Width with the Posted Jeight and use it as ratio. If Width is larger than 500 use 500 aspect ratio as default.

    ReplyDelete
  84. Hey Geeks!

    Arun Kumar - great job. I would make some semi-major upgrades to your code to make it more practical. Especially when it comes to ratio issue discussed above and autosaving on select end.

    INDEX
    Declare vars outside getSizes() function in SCRIPT section
    var x_axis;
    var x2_axis;
    var y_axis;
    ...
    var thumb_height;

    function getSizes() ...
    -----

    INDEX-> GETSIZES()
    cut everything ( ->> if(thumbs_width>1 ... <<- ) after thumb_height = obj.height;
    and add: return x_axis, x2_axis, y_axis, y2_axis, thumb_width, thumb_height;

    INDEX-> DOCUMENT.READY -> ADD NEW FUNCTION.
    I've added button SAVE IMAGE under the form instead of autosaving with prompt message (this was kind of annoying)

    $('#saveimagebutton').click(function() {
    if(thumbs_width>1) ... // paste this section
    }

    + in AJAX URL you have to add extra wars x2, y2 in order to get rid of ratio problem further

    And now the grand finale
    AJAX_IMAGE.PHP

    Entire IF condition updated as below :
    {
    extract($_GET);
    list($width, $height) = getimagesize($path.$img);
    $final_width = 200; // define your final target width
    $final_height = 200; // define your final target height

    // getting actual selection size:

    if($x2>$x1) // if-condition because user can select area from left to right or opposite
    $source_width = $x2-$x1;
    else
    $source_width = $x1-$x2;

    if($y1>$y2) // if-condition because user can select area from left to right or opposite
    $source_height = $y1-$y2;
    else
    $source_height = $y2-$y1;

    $new_image = imagecreatetruecolor($source_width,$source_height); // create new image basing on thumbnail selection size
    $source_image = imagecreatefromjpeg($path.$img); // generate source image for cropping

    $new_name = "newimage.jpg";

    imagecopyresampled($new_image,$source_image,0,0,$x1,$y1,$source_width, $source_height, $source_width, $source_height); // copy real-size selection from the original image
    imagejpeg($new_image,$path.$new_name,100); // create thumb image
    imagejpeg(imagescale(imagecreatefromjpeg($path.$new_name), $final_width, $final_height, IMG_BICUBIC_FIXED), $path.$new_name, 100); // scale created image to final_width and final_height and replace it

    exit;
    }

    Hope it helps.

    Cheers,
