Hi,
Were you able to see it in the editor before you saved the content? If you go back into edit view is it still there?
If you view the source of the page does the url for the image look correct?
If you uploaded it while using the VS Web server and then are trying to view it using IIS, it may not have got the correct file permissions or it may have the incorrect port in the url. If using IIS then find the file in the file system, right click it and make sure ASPNET user has permission on the file.
I've got to run an errand but will be back shortly and will look for new replies.
Best Regards,
Joe
