Upload er billeder virker i Visual Studio men ikke på server ?

Hey boy's and girl's :P

Har lavet en funktion til at uploade billeder og derefter komprimere dem, som virker når jeg køre den igennem Visual Studio uden problemer. Men når jeg så køre den fra serveren(Curanet) får jeg fejlen
fejl_1, som jeg har sat den til at retunere hvis "If File.Exists(fileUpload1.FileName) Then" ikke går igennem.

Hvis jeg så fjerner denne if sætning får jeg denne fejl ved upload af billede
