[Mediawiki-l] v1.12.0 - different image syntax?

[Tim Ware]

I'm using:

[[Image:image.jpg|thumb|200px|right]]

but it keeps throwing one of the values out of the resulting  
hyperlink. If I add in

|caption|caption-text

then the caption show up correctly. But with no caption, it does the  
weird thing.

Ideas?

Thanks!

Tim
