Hi Ranjan. Just open Nautilus and go to Edit>Preferences, Preview Tab and choose "Local Files" under "Show Thumbnails" for "Other Previewable File".
Jope this helps.
I assume you use GNOME and Nautilus.
The things u suggested were already checked & I think I was not clear in my question.
I can see thumbnails when I open home folder/pictures but I need to see thumbnails with open file dialog box

I need to upload image to imageshack then I click "upload image" a new dialog box opens up as shown in the above image that time there is no option to view files as thumbnails, that where I want to see thumbnails.
your quite wrong dude,
coz in linux there are different window managers(gnome, xfce, fluxbox,iceVM,etc etc) and file browsers(nautilus, thunar,konqueror, PCmanvm etc etc)
be carefull next time
I dont have thunar,konqueror, PCmanvm etc etc installed on my Ultimate edition 1.8 x64
I only see nautilus.
May be u meant that I have options to choose either of the above.
