The Photobox Plugin is a great timesaver, before I got it I had to export jpgs to a folder then go into the Photobox website and upload into an album from there. Now I just use the Lightroom export dialog to select the Plugin, set a few parameters and off they go. This has really streamlined my workflow and is well worth the money.
Version 1.5.4 is available for download.
This update fixes the issue with some of the albums not being listed, which in certain cases could prevent the export to a newly created album.
Visit the Photobox plug-in home page to download the update.
