Alter some Images

The web links have been provided in the attachment. The images have colored background. That needs to be removed and white background is to be given. Where models have been used, the heads have to be cut off from the images. The images have to be saved in JPEG format and the dimensions are height: 80 pixels and width: 670 pixels. There are few links where the back ground is already white so just modify the images from the web link and save as explained above. Each link has many colors. Save at least 2 images for each color of the same design. Back and front. If close up of the item is available in the links, save 1-2 images of that too. These images are for website listing. So pls be mindful how its should be. Sample will be given to you. There are about 20-25 links.
