Using ASP.VBScript how do I resize a picture that I have uploaded

Posted on 2008-10-24
Last Modified: 2012-05-05
I am uploading pictures to a server. Sometimes people upload pictures that are too large. I want to be able to resize the pictures to width='250' and the height= a size relative to the original image size. Right now my page can upload the image and retrieve it's dimansions which it stores in two variables called myWidth and myHeight. How can I resize the image? Thanks for any help. I have attached my code below if anyone needs to see it.

Here is the page to see what it does now:

<!--#include file="Connections/dsnvessels.asp" -->

<!--#include file="Upload.asp" -->


'Upload the image file and get reference to component

Dim Uploader, File

Set Uploader = GetASPUploader

'Use AddFile method to add file objects and change their properties as needed

Set File = Uploader.AddFile("file") 

'The the properties of the upload

File.ValidFileTypes = "pdf,jpg,gif,bmp,png"

File.MaxSize = 10240*1024

File.Overwrite = false 'Do not overwrite, create unique filename 

'Set the folder name to where the file will be uploaded to

Uploader.Destination = "Images" 

'Set longer timeout for large files if needed

Server.ScriptTimeout = 900

'Enable error handling to catch and handle errors during upload. For example, if user

'  cancels the upload or attempts to upload files of invalid (unallowed) type or size,

'  ASPUploader will raise an exception (error) with relevant description

On Error Resume Next

'Start receiving and saving file(s):


'Check for errors:

If Err Then

  'Redirect with error message

  Response.Write err.description


End If

'Add the details of the uploaded file to the database

Dim myFile, myDescrition, title, price, myWidth, myHeight, resolvedPath

resolvedPath = Server.MapPath(Uploader.Destination & "/" &

myFile="images/" & File.Name




Call sImageProperties(resolvedPath) 

myFile = Replace(myFile, "'", "''")

myDescription = Replace(myDescription, "'", "''")

title = Replace(title, "'", "''")

price = Replace(price, "'", "''")





response.write("<br />")



response.write("<br />")



response.write("<br />")



response.write("<br />")


set cadddetail = Server.CreateObject("ADODB.Command")

cadddetail.ActiveConnection = MM_dsnvessels_STRING

cadddetail.CommandText = "INSERT INTO products (ImageURL, name, description, price)  VALUES ( '" & myFile & "', '" & title & "', '" & myDescription & "', '" & price & "') "

cadddetail.CommandType = 1

cadddetail.CommandTimeout = 0

cadddetail.Prepared = true


'Finally, void the object

Set Uploader=Nothing 

Sub sImageProperties(vImage)

  Dim image, fs

  Set fs=CreateObject("Scripting.FileSystemObject")

  If Not fs.fileExists(vImage) Then Exit Sub

  Set image = loadpicture(vImage)

  myWidth = Round(image.width / 26.4583)

  myHeight = Round(image.height / 26.4583)

  Set image = Nothing

  Set fs=Nothing

End Sub

Slightly confused?  Normally you would just add the width tag to the <img> as below.

<img src="somepagethatgetstheimage.asp" width="250">

If you don't specify a height, the image height will be automatically adjusted to maintain the correct aspect ratio.

I am missing something?

@R Harrison: One problem is that if someone uploads a 10MB file, then all the users have to download that entire 10MB file for their browser to resize. If you get several of those on the same page..well then...that sucks.
I know a paid component isn't always the best solution, but I use aspJPEG. ( It does all kinds of image maniplulation include file-based (server-side) resize of the file down to a more manage-able size.

Yeah, but you can always limit the size of the upload... anyway that wasn't the problem stated.  If he wants to actually change the image to a smaller version then he will need an external component...

Yeah, that's why I think the general public shouldn't be allowed cameras greater than a couple of megapixels unless they get a certificate showing that the understand how to resize photos before e-mailing/uploading them. :)

With you on that one!  A 6 megapixal image squashed to 200 pixels, why oh why!

What you are trying to accomplish is very common.  I'm a PHP guy so I can't help you with your code, but if you google "asp image resize upload" you'll get tons of hits.  eg. there is a good tutorial for a free way of doing this here:
It requires .NET rather than classic ASP, but it looks straightforward to implement.
The particular example converts the uploads to PNG format, but you can change that to your choice.
There are also links on the page to several other related examples, and down in the comments section under "good article, but i have a better solution" someone posted another complete solution that looks pretty good.
