‘'Do you want to view only the webpage content that was delivered securely’’ IE 8 Warning
Actually I Experienced this issue while accessing a SharePoint site today
So why does this occur? when a HTTP based object, like a picture, is published on a HTTPS page Internet Explorer displays the following warning message dialog box before displaying the content.
Now the problem is that if you click yes here it will not show the picture and if you click no it will show. Since most of us don’t read the warning message fully will definitely click yes on the first instance 
How do I fix this?
- Open IE
- Go to Tools
- Internet Options
- Security
- Security tab
- Click Custom Level
- Under the miscellaneous section change Display mixed content to Enable (by default its on prompt)
