When you upload a photo the 'Add to Kwidget' box is already ticked for you and (if you choose to leave it ticked) the photo is automatically added to your kwidget.  If you have already uploaded a photo which you originally chose not to add to your kwidget and now wish to do so, please do the following... 

Go to your 'Engine Room' on your 'Home' page and select Photos > Manage Photos .  Look for the Photo you wish to add to your Kwidget  and then click on the 'Add To Kwidget' link next to the chosen Photo. 

The Photo is now added to your Kwidget. 

NOTE: You may also Remove a Photo from your Kwidget on this page by clicking the link 'Remove from Kwidget' next to the Photo you wish to remove.
