In Firefox 2.0.0.13 on Mac 10.4.11 there are some real pains with the image uploader.
I've tried uploading two images for a post. Fine. That works. Better than some it seems. I click on the second image, click "insert into post" and it appears. Fine. Now I want to add the other one, which I get to by clicking "add media". But clicking "show" next to that image gives no option to add that image to the post, only the option to "insert gallery to the post" ...
I'm still not even sure what a "gallery" is... I just want to be able to upload images and then choose where and when I insert them. I'm going to hold off on my brunt opinions, but this revamp of WordPress is anything but an upgrade. The old system was solid, reliable and effectively bullet proof. That was one of the main reasons for migrating from Blogger. Like some others, I'd definitely advocate the option to choose between the old and new systems. A transition period would give the WordPress techies more time to iron out bugs and less time dealing with all these complaints and questions. Six months down the line we'd be better placed to all move over. Was a beta period considered?
