Xara adding a boarder to Jpegs

[TimBox]

Hi,

I'm trying to overlay an image over another as part of a tile animation.

I have taken a section of the background then added a PNG with transparency over that and saved it as a jpg at the right resolution.

The issue is that it's being saved with an artificial edge. I can make the image in say paint.net and its not in xara. Any ideas?

Thanks Tim
