Removing the white background from an image

[Zakiyya]

Hi!

I know this question has been posted numerous times.

I am using Xara Photo & Graphic Designer 2013, but I still battle to use the color select and erase tool.

Can someone please direct me to a useful tutorial or video on how to use the tool or on any other quick methods to remove the background from a photo.

In this case I am trying to remove the white background. I need to place the wedding ring on a black background.


Thank you
