I tried it. Basically its working great. However the Exif data are sometime 
uninterpreted number values instead of strings. EG for a Nikon Camera there 
is a FlashpixVersion string which ist shown as 48 49 48 48 probably meaning 
1.00.   Other things like exposure time (and many more) are displayed as a 
fraction (10/200) instead of a clearer value (1/20). This kind of 
interpretation problems happen in many other EXIF tags as well.

I think to be able to see more it would be helpful if this problem could be 
fixed first.

Another thing is that I would to change the sequence in which the dataare 
shown. Atthe moment the Photography information part is somewhere in the 
midde wheras "Image Information"  and "Thumbnail" and "Iteroperability" are 
on top.I think the photography info is the most important and it would help 
to see it on top of the list.

Thanks a lot
Rainer
