The Google search engine on your mobile phone is a portable version but still has all the necessary features to enable you to perform a good search.
Of course you can still access the desktop version of google search on your mobile phone.However, you may have to do a lot of panning and zooming depending on your screen size.
This article briefly describes how you can do image search using google search mobile.
There are 2 ways you can access google image search. You can either go to google.com then click, images at the top of your screen. Or, just directly go to images.google.com. Even if you entered image.google.com, Google will still take you to image search.
In the image search bar you can type the title of the picture you want to search for.
Google search engine is very smart. For instance you can go beyond just searching for a type of picture. You can type both the title of the picture and the file type and click search. Let say you want to search for pictures of sand, in addition you also want the file type to be png. Then just type sand png in the search bar and images of different types of sand with file type png will be returned.
You can still go a step further and type; sand png 1280 x 720px in the search bar. The search engine will return different sand images of file type png and size 1280 × 720 pixels.
When you click on an image result, you will be given the option to visit the website that has the picture. If you click and hold the picture, you will be given the option to download the image.
Google has other tools that can help refine your image search. Just take a good look at all the options available. Picking the settings icon at the top left just before the picture results will give you the option of searching only pictures with creative common license. That is, pictures you can reuse without having copyright issues.
Also note that once you perform an image search, other search categories such as videos, maps, books, etc become available.
There is so much more you can do with google image search and indeed google search engine as a whole. I have written this short article to give insight. Feel free to explore google search and get the search you want.
