You can use a standard shape to turn your collage into, or draw your own custom shape.
Customise the background with any colour or add an image of your own.
Here is a quick sample I whipped up in a few minutes.
I could even drag and drop images out of iPhoto.
The quality is high enough to print out at a photo lab onto photo archive paper - even use as a poster to decorate a room!
If you upgrade to pay version, you don't have to look at the darn watermark (which sometimes moves to the bottom of the design but wouldn't for me today!)
Give it a try, its really an amazing and well thought out little application that is a lot of fun!
