Fehlerhafte Verlinkung, fehlenden PNGs - Anfängerfrage

[hydro]

Hi,

ich hab wenig Ahnung von der HTML-Programmierung, versuche aber eine von einem Bekannten erstellte Homepage anzupassen.
Bei der Sicherung der Homepage kamen folgende Fehlermeldungen:

17:36:29 Warning: Warning, link #243 empty

Die Grafiken sind scheinbar nicht notwendig. Sollte man die Links löschen oder ist das egal? Wie muss ich die Fehlermeldungen einschätzen?

Danke
