Final answer:
To change a JPG's background color, use an image editing tool to select and fill the background with a new color. Altering the photo's angle and zoom can help reduce distractions without editing. Pixlr offers free online editing tools.
Step-by-step explanation:
To change the background color of a JPG picture, you can use image editing software like Adobe Photoshop or free online tools like Pixlr. The process involves selecting the background area of the image and filling it with your desired color. However, if your objective is to take a photograph with a less distracting background, consider changing the direction from which you take the photo.
This can help focus on the subject by minimizing background distractions. Remember to zoom in as well to enhance subject emphasis. For editing existing images, you can use Pixlr's editor to crop or resize the image as necessary before uploading it to your blog.
