Teaser Image links current page if no link specified

[HitmanInWis]

If a teaser with no link has:

• Title specified -> NOT linked (correct)
• Image specified -> NOT linked (correct)

If a teaser with no link has:

• Title NOT specified
• Other fields like Pretitle and Description specified (never linked)
• Image specified -> linked to the current page (BUG)

Basically the image is linking the current page automatically unless the link is being suppressed by a Title being present. However, since Title is NOT linked in the case that a teaser has no link, the Image should also NOT be linked when it is by itself.
