Hey Cynthia,
Really glad you posted here for help and got the help you needed, thanks to RwmRS2. I just wanted to let you know about why it was transparent and how to fix that, for the future. The image from google is a JPG image (you can tell from the .jpg at the end of the URL), and JPG images cannot be transparent from what I know. To make them transparent, you can use an image editing program to "cut out" the render, or the person of the image.
A free, online, easy-to-use image editing program is
http://pixlr.com/editor. To edit out the render and make the image transparent using pixlr, here is what you would do:
1. Open the image from URL (

2. Click on the magic wand tool (

3. Right click, and click Invert Selection (

4. Now you have the person selected, you "cut" the person using Edit > Cut (

5. After that we just do File > New image, check the Transparent, and make the size 150x304, the same as the original (

6. From here we just click edit > paste and save using File -> Save
It may seem like a complicated process at first but it becomes routine

Hope I helped you for the future
