Image Uploading Problem

Jan 13, 2013 01:59 PM|LINK

Hi all,

This might not be the correct forum to post this in for which I apologise in advance. I urgently need some assistance with resizing and uploading images (JPG files) to my web server (Windows Web Server 2008 R2 with IIS 7).

I have a routine whereby users can select any number of images (JPG files) using an Obout File Upload control and then upload the selected images to the web server. Prior to uploading the images are resized according to specification and subsequently stored in the appropriate folder on the server.

This process works perfectly in the development environment: the images are resized according to specification and saved in the correct folders. However, in the production environment the images are not saved, despite it appearing that the resizing processes are completed without error (no error messages are displayed) the images are not saved in the correct folders.

The above leads me to believe that the problem resides on Windows Web Server and, or, IIS 7. I have triple-checked user permissions and can confirm that the relevant user account does have reading and writing permissions to the particular parent and child folders. In support consider that another process in the app has to affect that for each new record 2 new child folders (1 folder wherein images are stored and another folder wherein PDF files are stored) are created in 2 separate parent folders. The permissions on both parent folders are exactly the same. The process to create the new folders works perfectly in the production environment so too the process to upload PDF files.

The code being used is:

If fuPhotosAdd.PostedFiles.Count > 0 Then
            Do Until TempCounter = fuPhotosAdd.PostedFiles.Count
                Dim TempImage As New System.Drawing.Bitmap(fuPhotosAdd.PostedFiles(TempCounter).InputStream)
                Dim NewImage As New System.Drawing.Bitmap(TempImage, TempImageWidth, TempImageHeight)
                If Not Directory.Exists("~/Photos/" & txtRecordNumber.Text) Then Directory.CreateDirectory(Server.MapPath("~/Photos/" & txtRecordNumber.Text))
                TempPath = "~/Photos/" & txtRecordNumber.Text & "/"
                TempPath = TempPath & txtRecordNumber.Text & " " & FormatDateTime(txtPhotoDate.Text, DateFormat.ShortDate) & " (" & Format(TempPhotoCounter, "000") & ").jpg"
                NewImage.Save(Page.MapPath(TempPath), System.Drawing.Imaging.ImageFormat.Jpeg)
                NewImage.Dispose()
                TempImage.Dispose()
                TempCounter = TempCounter + 1
                TempPhotoCounter = TempPhotoCounter + 1
            Loop
        End If

Any advice?

Check the MaxAllowedContentLength size in your web config. That might be the problem.

<configuration>
   <system.webServer>
      <security>
         <requestFiltering>
            <requestLimits maxAllowedContentLength="100000000"/>
         </requestFiltering>
      </security>
   </system.webServer>
</configuration>
