How do I add text or modify an image?

In order to modify an image, such as putting your own text onto a blank label, you will need to open the image into your own image-editing or photo-editing software. Adobe Photoshop is a popular choice, but there are many others, such as CorelDraw, PaintShop and Photoshop Elements and for free you can use Gimp, just to give some examples.

Most computers already have a simple photo-editing software installed that will be easy to use and will work just fine for basic editing!
