<img src="module/products/imagehandler.ashx?r=1&src=<%=product.ImageFile%>"name="imgTH" id="imgTH" onclick="return img1_onclick()" height="358" width="320" />

module/products = path to your imagehandler

Ok, I am not sure about this part:

public void ImageResize(HttpContext context )

{

Image sourceImage = GetImageFromURL("http://www.ergona.se" + context.Request["images/productimages/"]);

double width = (context.Request["width"] != null) ? Convert.ToInt32(context.Request["width"]) : 100;

Is this right?

The images wont show up:

Okay here we go:

Create a file called ImageService.ashx

Copy and Paste the Code from BEGIN: to :END into the file

BEGIN:

<%@ WebHandler Language="C#" Class="ImageService" %>

using System;

using System.Web;

using System.Collections.Generic;

using System.Drawing;

using System.Drawing.Drawing2D;

using System.Drawing.Imaging;

using System.Net;

using System.IO;

public class ImageService : IHttpHandler

{

public void ProcessRequest(HttpContext context)

{

if (context.Request["type"] != null && context.Request["type"] == "r")

ImageResize(context);

// add logic for other features such like Headline generated etc.

}

public void ImageResize(HttpContext context )

{

Image sourceImage = GetImageFromURL(context.Request.Url.AbsoluteUri.Substring(0, context.Request.Url.AbsoluteUri.ToString().IndexOf("ImageService")) + context.Request["src"].Substring(1, context.Request["src"].Length-1));

double width = (context.Request["width"] != null) ? Convert.ToInt32(context.Request["width"]) : 100;

double sizeFactor = width / sourceImage.Width;

double newHeigth = sizeFactor * sourceImage.Height;

Bitmap newImage = new Bitmap((int)width, (int)newHeigth);

using (Graphics g = Graphics.FromImage(newImage))

{

g.InterpolationMode = InterpolationMode.HighQualityBicubic;g.DrawImage(sourceImage, new Rectangle(0, 0, (int)width, (int)newHeigth));

}

newImage.Save(context.Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg);

}

private static Image GetImageFromURL(string url)

{

HttpWebRequest httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(url);

HttpWebResponse httpWebReponse = (HttpWebResponse)httpWebRequest.GetResponse();

Stream stream = httpWebReponse.GetResponseStream();

return Image.FromStream(stream);

}

public bool IsReusable

{

get

{

return false;

}

:END

The Url which Calls it is case senstive!

The image src sounds like this:

http://localhost/ImageService.ashx?type=r&src=~/repository/content/sample.jpg

>Test it and give some feedback pls.

Cheers
