The Google Images service oldtera had a very useful "search by size" option in the advanced search to help you find logos, wallpapers and other images on the Internet at their exact size (or resolution).
For example, you could limit your search for landscape photos to archives picturewith a size of at least 10 Megapixels. 
Alternatively, if you use Google Image Search to find desktop wallpapers, you could set the image resolution to 1920 × 1080 pixels, and Google would return large images with only those exact dimensions.
The "exact size" search option is no longer available in Google Image Search, but you can still specify the size of the images in your searches using a search algorithm command.
See how.
Open the address images.google.com and enter them conditions αναζήτησης όπως το κάνατε πάντα. Στη συνέχεια, προσθέστε το imageize:ΜΗΚΟΣxΥΨΟΣ στο ερώτημά σας και πατήστε Enter. Η Google θα διαβάσει την πρόσθετη εντολή στο ερώτημα, θα το αφαιρέσει, αλλά τα αποτελέσματα θα εμφανίζουν μόνο εικόνες που ταιριάζουν με το καθορισμένο μέγεθος.
This resize search also works in Google's version of cell phones. So you can use this simple trick to find the perfect wallpaper size for phone you.
