Basically, the uploading process seems to work.
1) Then you can pick to put the uploaded pics to new folder or an existing.
BUT if you click one of the pics to look at it, or if you click on "Upload images" again (or something else), the pics are gone. No "Unsorted folder" yet
2) Uploading to a new folder:
After typing a new folder name (like "test" in my case) and clicking the button "Move to new album", I get this (click to enlarge):
First, the pics appear vertically stretched. I can't pick the codes for single uploaded pics, only for the whole album, and only as medium thumbs. I have to return to the album menu, then I get this:
I can't enter the album by clicking on the "preview pic" of the album, since there's no pic selected yet. I have to enter by clicking on the button on the bottom left below the album and select one manually.
