Sorry, I guess what I meant to say was the amount of data displayed.
If you look at this one:
http://www.oneuk.f2s.com/photos/displayimage.php?pos=-210 this is some of the info it displays:
Exposure Program: Manual
Exposure Time: 4/1 sec
FNumber: f 29
Flash: No Flash
Flash Pix Version: version 1
Focal length: 27 mm
ISO: 100
Make: Canon
Metering Mode: Multi-Segment
Model: Canon EOS 350D DIGITAL
Whereas this one:
http://www.oneuk.f2s.com/photos/displayimage.php?pos=-212 only diplays the following:
Filename: C_IMG_1796.jpg

And then this one:
http://www.oneuk.f2s.com/photos/displayimage.php?pos=-216 displays the full set of data: (some of which is:)
Exposure Program: Unknown: 0
Exposure Time: 1/500 sec

Flash Pix Version: version 1
Focal length: 18 mm
ISO: 320

and any others since the one above (216) only display the lesser amount of data.
I was thinking if it was anything to do with whether I take the photo on manual or auto, but I realised that the first one was taken on manual, and the other two were taken on auto (or at least semi auto)
