BOGEN  It didn't crash again since. Also there doesn't seem to be an API for syncing back tags, so it's unfair to blame this on iP2F … (Leaves the window height as main point of critique …)

BOGEN  I like it. It gets the job done. And it's less expensive than FlickrExport (which IMHO costs too much for a mere export plugin).

Minor gripes:

1) While iP2F can sync back title and comment changes back to iPhoto, it doesn't do this for tags. (Why not …??)

2) The window is too high for iBook and 12" PowerBook users!

3) Possibly led to an iPhoto (6) crash once.

TOMJOECZAK  Stronger alternative to Flickr Export to iPhoto. Buying during Beta period made plugin an even more cost-effective choice. Might be nice to see a "Create New Set" option in Add To Set pulldown menu; the type-to-create a new set threw me a bit. Keep up the good work.

GNAIHC  I've always wondered if there will be another Flickr export plug-in. People seem to like FlickrExport and rave about it. However, I am never really a fan of its interface. So I am glad, someone finally steps up and release a new Flickr plug-in not only has all the features I need but looks great. IMHO, iP2F looks more integrated with iPhoto than others. Looking forward for future updates!
