Thanks Sergey,
It works now when wrapping a PNG byte[] in a ByteArrayInputStream.
It doesn't work wrapping a JPEG byte[]. I guess thats a problem with
the image encoder - nothing to do with CXF at all. I could create
download, save it and look at it with PaintShop Pro and it was
fine, but it wouldn't load in iether IE or firefox as a JPEG.
Mission accomplished!
Thanks again.
Doug
