hi.........

 u r not passing the file(image) which you uploaded.

<strong>newimageid = ImageUtils.uploadImage(Title.Text, CInt(AlbumList2.SelectedValue), FileUpload1.FileContent)

in this FileUpload1.FileContent is content of the file(image) which u uploaded but not the file.So,that u r geeting the error,try to pass file(image) insted of content like FileUpload1.PostedFile

Solved the problem i had not changed the connectin string over in one of the classes so when i compiled the site things like the image handler would not work properly as i had the wrong connection string.
