I was very excited for 2.0 and it's image capabilities but right now I have a few problems with it.
No folder structure when you upload them to say put some pictures in some folders and catagorize it. These folders are only viewable when your rummaging around on the post screen. If this is put in then also the ability to drag and drop them from folders and organize at will.
Multi-Image uploading like in Flickr and G2. I want to control all my images from one handy place, WordPress.
Ability to rename/edit pictures. As it stands you can't rename pictures or edit their description.
Now a question: how do I add thumbnails? I can't find a thumbnail option and some pictures show as a thumbnail when I want them to show as a whole picture.
Now a problem: when I try and edit some pictures in the editor and say seperate them by a space, there's a little line inbewteen them. I can't get rid of it. Sometimes the images will act finicky too and not move around correctly and sometimes a wrong action can delete them.
Now don't get me wrong I like the new editor and the images are an awesome addition. Just could use a bit of work.
