I usually don't mass import files to my gallery, maybe 5-10 at a time so having more than 1 browse button to upload photos to my gallery at once would be a lot easier than 1 photo at-a-time.
Anyway to accomplish this?
I think after this is done, plogger might be the BEST gallery on the web right now.
That's something that we're looking into for a future release. There's a Trac ticket already open for this task so you can follow the progress.
In the meantime, you can upload a zip archive containing 5-10 images via the Upload form, or you can simply FTP the images you want to import to your server, placing them in the plog-content/uploads/ folder, and going to the Import page in your admin area to finish importing them to your gallery.
