Could not find part of the file path

Question

I've come across which states that part of the file path cannot be found. I'm fairly new to coding, but is this mistake obvious?

I've created the same application before off a USB

Which works fine, so quite confused as to why the application on my machine isn't.

Error message itself

Update - thank you for the comments so far.

Assuming you want the relative directory of \Images you want to change line 33 to:

filename = Path.Combine(Server.MapPath("~/Image"), fileName);

You are missing the tilde '~' to make it relative.
