This issue has been present since Flickr sync was introduced. Only some of my images sync - so yesterday I had a set of 31 images in an album but when I uploaded them there were only 24in the set on Flickr.
So I look at the set in Aperture - it says there are 31 images - on Flickr there are 24. So I sync again. Now there are 28 but two of them are duplicates.
I sync again and all 31 are present along with another duplicate but the colours of two of them are reversed (negative). I tried the same thing with Facebook with very similar results.
I've been struggling with these errors for months. I've sent my database to Apple at their request - but no reply - I can only assume they thought the upgrade to 3.1.1 had fixed the problem. Well not for me or for this user

Hence my somewhat plaintive request for a Flickr sync process that works.
A simple upload function would be a better option - so that once the image is on Flickr it remains there unchanged rather than the dodgy sync function which requires me to use Aperture as my Flickr manager rather than just an image processor. Flickr is quite capable of being managed through a browser with this frustrating and flakey process built into Aperture.
Thankfully there's Flickr Uploader for Aperture.
