Add a signiture as picture

[TheuRe]

Hey,
I would like to add a signiture in the coverletter as any picture/scanned file.
If I add a picture with \includegrafics{xxxx.xxx} I get a bad scaling and spacing, anywhere I include the command.
Is there any command already included or how can I can manage the issue?!
Regards
