how to search wallpapers using resolution?

use windows search. in windows explorer, click on the search tab. click on pictures, music or video. check the pictures and photos tab. click use advanced search options. select the radio button next to specify size (in kb). on the left side, let it be set to at least and on the right size enter the minimum size. for example, if the resolution of the images you want to search is 1024*768, enter 150 as the value. if it's lesser than that, set the value accordingly. the results may not be accurate, but u will get almost all the images. or else u may want to try google desktop search. it searches for files faster and with more accuracy than the windows default search. i think it will allow u to search for images by resolution.
