I want to upload my photos in the net through google images and i don't know how to do this. Can anyone help me on this? thanks in advance.
What do you mean? Do you mean you want your photos to appear in google images? In that case, google will crawl your site in their own time, the same as any other google listing. You can help your images get listed for what you want, with good alt tages, file names and text around the image, but other than that, getting the page you want to be noticed by google is the same old same old - backlinks.
There is also a setting in Google webmaster tools where you can choose whether or not to allow images to be indexed there.
