You can model your part whatever 3D Shape you want then click on your model. This will open a quick select window and you want to select the appearance icon (looks like a beach ball) select the top level face selection and this will open up your appearance screen. In the color / image tab which may open as default there is a appearance file to path with a link for images. Select the browse option and go to the image you want to apply to your model. Once you select it Solidworks will save this as a .p2m file and apply your image to the face of your model. You can then size, and rotate to make the image as desired. Attached is an example of it attached to a simple ball and showing several of the images. Sizing will result in one larger image instead of multiple. Hope this helps you could also make the image into a decal and apply it to the model.
