One of the reasons we are experimenting with Plogger is to simplify managing and sharing large quantities of files.
It seemed like a lightweight solution that had enough features to serve the purpose.
We are still experimenting, but hopeful that Plogger will be suitable for the task.
re: uploading/importing images
The current "Import" mechanism seems to work OK, but...
the import page display of thumbnails and processing is inappropriate for bulk uploading- for example, try uploading hundreds or thousands of images in one batch.
Cancelling the page loading both before and during importing seems to be a possible work-around, but one wonders if there are problematic side-effects.
Please consider an improved streamlined workflow for handling large numbers of files...
