Google is by far the most popular search engine with billions of quieries conducted each year. The image search engine works in a similar manner to the normal search results. Google first discover a web page on the internet and extracts an image from that page and includes it in the search results. They try to understand what the image is of by looking at keywords around the image.
Things You Will NeedIf you are looking to upload images or photos directly to Google then I am sorry that will never happen, Google is a search engine and not a place to store images.
You can get your images in the search results by following the best practices I have outlined below:
Step 1You need to store your photos or images on the web somewhere. That could be on your website, your blog or on an image storage site such as Flickr or Picasa.
Once you have the ability to store images on the web, move onto step 2.
Step 2Before you proceed I strongly suggest you backup your images, just in cases anything goes wrong. Just put your images into a folder and "right click" select "copy" and then "paste" the new folder somewhere safe, like your desktop. Always keep a back up copy in case you lose or corrupt your files.
Step 3By now you should already have a place to store your images on line and have a back up copy on your pc. So let's start. Locate one of your images in its folder and "right click" on the icon then select "rename" you should see something generic like 665011.jpg, you need to rename this file, use between one and five words and make sure those words describe the image. So if you have a picture of a really fat black cat you would write something like this: big-fat-black-cat. jpg
(please do not rewrite file names if you have already uploaded your image to a website, you may get a 404 not found error)
Step 4Now it's time to add this image to your website or upload to Flickr or Picasa. You should follow the instructions at Flickr/Picasa/your host etc. However it is really important to include some keywords in the text around the image so search engines understand what the image is about.
Make use of the "alt" tag, this is where Google looks for keywords, if you have the ability to write an alt tag do so, the finished line of html should look something like this:
img alt = "A photo of a big black cat I saw last year"
Also try to include a description of the image in the webpage. Google does look at the text around the image.
For non webmastersIf you don't have the ability to write html, just include some descriptive text around the image, whether that be on a webpage, in the description section in Picasa/Flickr, it doesn't matter.
By now you should have your image file renamed to something descriptive, it should be uploaded to a public website and have some descriptive text around the image, or at least somewhere on the page.
Now it is just a case of getting/waiting for Google to visit the webpage and see the image. You cannot request Google come and check out your page, everything is done automatically. You can however speed that process up by getting some links to your webpage. Google looks at links on a web page and "follows" them. That is how they locate new pages on the web.
You could create an article here on Info Barrel (like this one) or like this article on the Hubpages website.
Once Google have visited the page, they will extract the images and include them somewhere in the search results.
Things that can go wrongYou uploaded your images to a website but blocked search engines with strict privacy settings.
You included adult words on the web page and now Google has blocked images from the page as they are unsure as to whether they are adult in nature.
You keyword stuffed your page in an attempt to get the image to show up for your token phrase/keyword.
The image is copied from another website and Google's duplication filters have blocked your image from appearing in the search results.
