Topic: Thumbnail views all off center.

Hi all

I am wondering if there is a way of changing how the thumbnail is formed from the original picture. 

It appears that the thumbnail is the top left view of the original picture, which for me often results in the thumbnails being indistinguishable (e.g a blue section of sky, half a person's face etc).

I've tried to make my own thumbnails, using the same size as the thumbnails made by simpleviewer & then putting them in the thumbs directory, however the program does not recognise these.

Any ideas?
cheers
