How to stop 'Gallery' app in Xperia Go from showing up the screenshots of downloaded videos ?

[xperiafan1]

Gallery app in my Xperia Go shows the screenshots of downloaded videos and Whatsapp images by default. I tried the following but no luck and I dont want to reset to factory settings .

1) Deleted the cache from 'Manage App' for Gallery + phone restart.

2) Added .nomedia file to whatsapp images directory and 'download' folder using ASTRO so that the app ignores loading pics.

3) when 1 and 2 didn't worked I searched and deleted all video screenshot pics from .thumbnails folder under DCIM directory and cleared the whatsapp images directory as well , repeated (1) above , still accessing galley loads all pics from somewhere.

Appreciate any help on this

Figured that out , deleting the cache directory contents inside /mnt/sdcard/Andriod/data/..*gallery* folder does the job , though it still shows blank thumbnails listing how many videos were downloaded etc.
