Most websites have a generic size wallpaper. A sort of one size fits all, if you will. The i95, 730 and 830 all have a different size screen. So the same image would have to be on a website 3 times. Download and install a little (free) program called irfanview. I have a copy on my site. Open the wallpaper or any picture in the program. Click image (top leftish) and then choose resize uncheck preserve aspect ratio. There is the size of the file now. Adjust it to your taste. Each size should be between 100 and 150. So 130 x 135 would be valid. It also must be 256k colors. That option is also in the image menu choose decrease color size then choose 256k. Save the file as a gif format and you are set. OH important the total disk size of the file must be under 15k. Right click the file and click properties to see the size and you can have to many wallpapers. 10 - 15 is about max.
