MAMP, File extension, and server path

Ignore: In the publish form I’m being told at the File field that I haven’t defined a server path, though it seems I have: /Applications/MAMP/htdocs/wac/images/uploads/

Ignore: I’m developing in MAMP on a Mac.

Edit: Urgh! Nevermind, I found the answer (simple) searching the forums. Duh!
