Hi ishwaryaa, I hope I can help you. Okay, first of all you have to decide what picture you would like for your hub. For example say you write about a town or city and would like a picture of the main street. All you have to do is write in the name of the town in the search box like you do when you want to find out anything on the web. When you get your google list of answers click on the words along the top of the screen that say images. This will bring up all the photos of the town you have googled. flickr is a good site to get photos but the best thing to do is write in the search box above the photos the exact name of the town, road or person you would like, followed by the words Public Domain photos. This way you are allowed to use them without copyright being a problem. When you see the picture you would like to use, just click on it and it will open. Then right click and choose save too.... this will open your gallery box on your pc and just press save. When you want to use it in your hub go into Edit mode, open the photos edit box and click on the green button this will open up your gallery and then all you do is click on your photo that you need and it will appear in your hub, okay?
