How to create thumbnail at image upload time.

Hi , and thank you in advance for your help.
I have my image uploading to a server and the image file name stored in MySQL database successfully with the following code. Now I need your help on creating thumbnail for the same image that is being uploading and stored it in different directory (called "thumbnails" for example). Here is my working code without thumbnail creation feature.

Thank you.

<head>
<title>Upload an image</title>



<link href="style.css" rel="stylesheet" type="text/css">

I've always used CFX_Image -  easy to use ..
<CFX_IMAGE ACTION="RESIZE" FILE="#ExpandPath('sharedimages\#file.serverfile#')#" OUTPUT="#ExpandPath('sharedimages\optimised\#file.serverfile#')#" X="135"

but recently started to use imagemagick, the problem with Imagemagick is that you have to have CFExecute turned on in the admin settings and on some shared server (in fact most that I've ever dealt with) have it turned off. All you are doing with Imagemagick is passing an execute command to an application on the server.

Something like ... <cfexecute name="#executablePath# mogrify #extension#" arguments="-geometry #width#x#height# 75 #filename#"></cfexecute>

(basically what you would put in DOS to make it work)

In my opinion, CFX_Image does the job simply and easily (although I've had no joy with progressive JPEGs) although, I find the image quality of those done with Imagemagick slightly better

Hope that helps :)

I used following .pl script with ASP and it works fine on resizing my images. This is my first experience working with ColdFusion and images and I would appreciate if you take a quick look at the following. Please let me know what could be wrong with those. I get my action file running but it does not resize and stores anything. Thanks.

you can use custom tag.
We are using the tag cfx_imagecr3 free from some web site of searched through google. If you are using in your code this tag pls replace with the new tag.
 
The usage:
<cfx_imagecr3 load="photo.jpg"
              save="photosmall.jpg"
              resize="158x" quality="70" nocache="1">    

It should be very easy.
