Image Buddy is a cool little app. What appealed to me most was the ability to create a collage of photos on a single page, apply masks to each photo independently of the other and then be able to print the collage. However I was very disappointed to discover that you cannot free-rotate, or specify increments of rotation other than 90 and 180 degrees. This unfortunately makes it a deal breaker for me... but maybe not for you.

The sperately downloadable documentation is very well done and quite complete.

Add free-rotate capability and you've got my order.
