client side image resize?

Cr8or

The age old problem of large images and low bandwidth has come up again ..
I have tried to get the person to resize images manually however it seems like alot of extra work to them.

Im looking for a client side way of resizing images in a browser before uploading to a server .. anyone got any ideas?

I've seen a few java solutions that might do the job but im looking for something open source or free.

I asked this about a month ago - didn't get much of a response. I'm going to use max file size to prevent abuse and then I will resize on the server.

On Windows, resizing with Microsoft Paint is really easy.

• Launch Microsoft Paint
• Open image
• Ctrl-W (Image, Stretch/Skew) to resize. Enter same percentage (<100%) in each box.
• If new size is good then save, else Ctrl-Z (Edit/Undo) and choose a different percentage.

What language are you using PHP (look into GD library) or asp (check ASP Upload)

You're much better off doing it server side and once off rather than on the fly.

PHP has some great functions, but as per louie's post, you will beed GDlib. Most hosting companies will have this installed.

Here's a sample of code we use on a site:

[PHP]

$uploaddir = '/yourpathtoimages/';

$t = time();
$uploadfil1 = $uploaddir .$t.str_replace(" ", "-",$_FILES);
$main_image = $t.str_replace(" ", "-",$_FILES);

$uploadfile = mysql_escape_string($uploadfil1);
if (copy($_FILES, $uploadfile))
{
$msg= "File is valid, and was successfully uploaded. Record inserted.\n ";
}
else
{
$msg= "Possible file upload attack!\n";
print_r($_FILES);
}
$typ1 = str_replace(" ", "-",$_FILES);



$small_image = "small-".$t.str_replace(" ", "-",$_FILES) ;
$image_attr = getimagesize($uploadfile);

//echo $uploadfile . " ";

$size = 75;
$percentage = ($size / $image_attr[0]);

// Get the new image size
$width = round($image_attr[0] * $percentage);
$height = round($image_attr[1] * $percentage);

exec("/usr/bin/convert " . $uploadfile." -resize ".$width."x".$height." ".$uploaddir . $small_image);
[/PHP]

problem is he is uploading high res images and his on a slow connection so he would have to wait for ages for them to upload.

http://upload.thinfile.com/image/ seems to do the job it changes the size then uploads.

Microsoft have a freely available utility that plugs into windows and allows you to resize images from within windows explorer, it's called the Image Resizer Powertoy and can be downloaded via this link: http://download.microsoft.com/download/whistler/Install/2/WXP/EN-US/ImageResizerPowertoySetup.exe
