@alentsch I tried the JPG, but I am not seeing any bands in the embedded image. The embedding strength is also 100%. I guess that Flickr would be doing some changes to the JPG and so I am not able to reproduce the issue. Would it be possible to attach the original images here?

@syvaidya thank you your reply. I attached both images now to this message - sorry I didn't know that attaching files was possible - much easier of course. When I check the watermark with the command $ java -Xmx1024m -jar /usr/share/openstego/lib/openstego.jar checkmark --sigfile=xxx.sig --stegofile=xxx.jpg I get a strength of 0.5 (50%) for the attached image. Where the image "turns into blue" (not in the original) there are also some boxes, which are not in the original image.
Thank you very much for your help again!

Was this fixed now?
Or does OpenStego still have this problem?
