Thumbnails no longer viewable

[karlos130]

Can anyone tell me what I have done ??
Ive got an iMac on Mac OS X 10.5.8

for some reason my JPEG files no longer show as a picture, so making flicking thru them is very difficult as i have to open each one.

Once they have been through PS they show up as JPEG's then.

The only things I have done different recenly is to re organize my files and numbering using Bridge and also exporting from lightroom using export rather than burn full size Jpegs

am i missing something here but none of my files show the picture no more when flicking through them

I guess the first thing to check is that "View -> show view options -> show icon preview" is ticked.
