I successfully created set of control classes and dropping them in a form. The control classes are displayed well with images but when running the system my system I have this exception error:

An unhandled exception of type 'System.Security.SecurityException' occurred in mscorlib.dll

Additional information: Request for the permission of type System.Security.Permissions.FileIOPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed.

Debugger actually is pointing to the line of code that should get the image file.

this.image = System.Drawing.Image.FromFile("\\Images\\ok.ico");

Am I missing something guys?
