How to use PNG with transparency as "photo frame" for bitmap in Xtreme Pro 5?

[yuriA]

Hi,

Can you please help me to find out how to use PNG with transparency as "photo frame" for bitmap (photo) in Xara Xtreme Pro v5?

I'm try to design pages for photo book in Xtreme. I have set of files in PNG format as "frames" for photos. For example, I attach one (14_v.png) to this message. In another editor I can use them as "masks" for photos - in second attach (capture.png) you can see on left - usual photo, on right - photo with mask as photo frame.
How I can make same effect in Xara Xtreme? I try to use different modes, substract/add shapes and other - but no luck. Can anybody help me with advice, how to make it?

Sorry if this question already asked - I try to use search, but can't find answer.

Thanks for ahead and sorry for poor English.
