It can use the same .fotobilder.conf files as the perl client. On Windows it usually expects to find this file in C:\Documents and Settings\winloginname\fotobilder.conf
It can upload *single files* to one or more galleries - there is no directory upload mode yet. It spits out debug info by the bucketload, some of which could even be comprehensible. It is ALPHA CODE and will almost certainly gain sentience, try and take over the world, and make lascivious comments towards your parents!
Note that the archives on that site contain a lot of source code that's nothing to do with the client, so ignore it. I might make a seperate build script that only exports the relevant files later.
See http://www.phase.org/files/INSTALL for install details.
Please note that I can provide NO SUPPORT for this, although I will of course be reading this community as I test the fotobilder code!
Any comments on whether the use of the 'fotobilder' name in the client is appropriate - or any similar issues - are welcome.
