Google’s custom background feature is being put to good use by Azunyan fans it seems – truly, Google has never been so moe.
The option for a custom background image is available from the bottom left link on the main Google homepage.
Those looking for high resolution images for this or general wallpaper purposes can find them using the advanced search features of the Channel – width:1280 will search for images with a width of exactly 1280 pixels, whilst width:3000.. (with two periods after the number) will search for images over the specified size.
A rating:safe can be applied if less prurient imagery is desired.
The same technique works with “length:” and the two can be combined together – other power search features are outlined in the search quick guide, seemingly little read despite being linked on every page.
