I've posted something like this before but i was never able to get it to work...

I'm drawing to a new bitmap in memory, converting it to a stream and loading it into an AtalaImage.

 At this point, I'm attempting to copy exif tags into the image using JpegMarkers and populating the Thumbnail memory stream with a smaller version of the image, in stream format...

I then save the image and it shows up entirely corrupted.  When I try to parse the exifcollection back out of the image it shows that there are thousands of exif properties.

Can you post some of your code here?  Or alternatively you can create a support case with us.  The MetadataDemo that is included with the SDK might also be able to help you, as it has the capability of editing EXIF data and adding thumbnails.  Does it work when you use the demo?
