How to create WVGA wallpaper with IrfanView FREEware.

Open photo in IrfanView, go to ‘Edit’ menu and select ‘Create Custom Crop section…’ or press Shift+C (shortcut key).

Then select ‘none’ in the ‘Set ratio for width: height:’ column and select ‘pixel’ then enter ‘Width:’ 480 and ‘Height:’ 800 in the ‘Selection size/position:’ column.

Crop and resize photo software.

I use Irfan View to create WVGA wallpaper. I found that Irfan View allow you to customize your crop aspect ratio and dimension. Another good thing about Irfan View is its FREEware, to download click ‘Irfan View’.

You also can use Google Picasa to crop and resize photo but Picasa wouldn’t let you custom crop, you only can select a preset aspect ratio 16:9 and export an edited photo to resize it. This preset will not generate an exact resolution 480x800 instead its will converted to 450x800. Nothing wrong with this resolution, its still can fix nicely in your device it just that your device will stretch the photo to fill the missing pixel. You and your friend may not notice it's. This method still work and I will share both methods.
