image sometimes appears, sometimes does not

 Hi,

My database has a products table that has images stored in a varbinary(MAX) column.

I'm trying to display product information in a repeater and trying to display the images as well by using a GenericHandler class but I can't get the image to show up in my page.

Here is my Handler.ashx class:

Public Class Handler
    Implements System.Web.IHttpHandler

    Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest

        '== Set up the response settings
        context.Response.ContentType = "image/gif"
        context.Response.Cache.SetCacheability(HttpCacheability.Public)
        context.Response.BufferOutput = False

        Dim id As Integer = -1
        Dim stream As Stream = Nothing
        If Not String.IsNullOrEmpty(context.Request.QueryString("id")) Then
            id = context.Request.QueryString("id")
            stream = GetImage(id)
        End If

        Const buffersize As Integer = 1024 * 16
        Dim buffer(buffersize) As Byte
        'byte[] buffer = new byte[buffersize];
        Dim count As Integer = stream.Read(buffer, 0, buffersize)

        While count > 0
            context.Response.OutputStream.Write(buffer, 0, count)
            count = stream.Read(buffer, 0, buffersize)
        End While

Hi there,

Can someone help me on How to insert Image (jpeg) into MS Word Programmatically using VB.NET..not C#.NET???

I could hardly find any articles for the coding. Preferably using Bookmark...can i have the sample code.

Thanks,

I have a piece of code that writes string into an image and save it. It works on one of my site and but not the other. The image.save is not working. If this is a permission problem, which account should I change? I use win server 2003 and IIS 6, and have given ASPNET, NETWORK SERVICE, and anonymous user write access.

I am trying to get the height and width of the image dynamically.  The reason is I am loading multiple images using code, where the image name is from the database. 

Here is my code:

in the ascx page, I have an asp image

<asp:image id="imgInfo" runat="server" /> 

In the code behind

string ImagePath = "~/products/img/" + dataviewImgInfo[0]["imgName"].ToString();

System.Drawing Image imgProd = System.Drawing.Image.FromFile(ImagePath);

if(imgProd.Height > 200)

WHen I run this page I am getting the folloiwng error

Hi everybody

I'm creating a website where it must  be able to upload, crop and resize images. This works until I use transparent PNG images. When I upload a transparent PNG, the transparency becomes black. I've searched the whole internet, but found no solution so far. Can someone help me? This is my code. I'm working with MVC 2.

			try {
				HttpPostedFileBase file = Request.Files["image"];
				file.SaveAs(Server.MapPath("/Uploads/" + file.FileName));

				ViewData["ImageLocation"] = "/Uploads/" + file.FileName;
				return View();
			}
			catch (Exception exc) {
				return RedirectToAction("UploadImage");
			}
