Hi!..
Just to share with you all people the following information for 6630:
- Exact Wallpaper size 174 x 142 pixels
If you want the best image quality on your idle wallpaper, make your own image
at that exact size to avoid phone system rescale (will look blur if phone does that)
- Exact Contact Thumbnail image: 45 x 47 pixels
To get the best image quality again, make your own image at that exact size, and save as JPG, transfer to the phone, then assign that image to any contact, only with JPG the phone system will create a good dither on the images, don�t use BMP or GIF, will look very bad.
Well...
hope you will notice the difference on quality using this match image sizes..
cya!
