Tom asked for a solution in his blog for exporting photos from iPhoto to Flickr. Since he closed the comments on his blog post (for whatever reason that is) I’ll try and answer the question via trackback.
There certainly is a solution to exporting photos from iPhoto to Flickr. The excellent FlickrExport which I already use for a long time. It’s a clean and easy solution and really integrates nicely with all of iPhotos functions.
So give it a try, Tom 😉
