How can I upload a picture to google images?

Thank you

you cannot upload your photos to google images like you can do to photobucket and other photos hosting companies...

Google images are actually the pictures at websites which are crawled by the google and show them directly rather than showing the website(even though you see the link of website where original source of picture exist).

If you want your picture to be posted on google images, i would suggest to make a website and put the photos and then add your URL to google engine but it is a time taking process, takes many days for google to find your address and allow google image to show the pictures of your site.

You cant upload images to google images.
Images are just like sites, when you have a site that have pictures google bot will scan the site check the alt of the pictures (the alt is an html code givin to describe the picture) and add it to database eventually it will get to google images section, and then by some algorithms get ranked to be in first pages

You can submit your site which host the images to google. Google will later crawl your site and include images and texts on your site to it's search results. The url to submit is here http://www.google.com/addurl/ . Remember to give meaningful names to your images so that google can index them properly.
