Sorry, I was tired I thought it was the OpenWRT thread.
In the case of the Raspberry after mounting the SD card .img file the html files are in /opt/PirateBox/www. Have you tried editing these files? If you have already written the image file to the SD card, then all directories should be openly accessible when you insert the SD card into your computer. There should be 2 partitions in total, the larger one (2 GB) contains the files.
I don't thin it is possible to let the user decide where to upload for the moment either.
