I've an image of M106 that the Flickr bot has blind solved for me, but the orientation when viewed in World Wide Telescope is completely off - the reason for this appears to be that orientation is wrong for this image for some reason (and is different to the orientation from the results of the upload to nova.astrometry.net myself). The image has south approximately up, so the Flickr results appear very odd to me, though the object tags in Flickr *are* correct....  is this a bug in the way that the Flickr bot handles the results? (I've seen a similar issue on some other images I have on flickr, but not all...). 

Links to the two images and the relevant results as follows:
