:O what does that mean, the content of "What I have tried" section?

I'll bet you the error tells you exactly why it failed. And I'll secondly bet you that it is a permissions issue.

Your previous location will work because the uploaded image files are stored within your website root folder which has proper permissions configured in IIS.

Your new path for upload is hosted outside of your website which why you are getting error (e.g permissions error). To overcome that, you would need to setup a virtual directory (with the real directory where you want it) and in IIS ensure that there is no direct access to that folder (paying particular attention to read and directory listing permissions).

PS: As a general rule, work on the principle that what belongs to the website should stay within the wwwroot folder structure, just as (for example) what belongs in "C:\Windows\System32" shouldn't go in "My Documents".
