[montu]

Hello,

when printing multipe picture on one page with page layout 'Thumbnails', and captions on, there is a big gap between the picture and the caption.

This happens only when colums is higher then 1.
The glitch would get better when row goes up.

First I recognized this in XnView 2.32 and it's still the same in 2.33.
Can't say if the problem exists before 2.32.
