Note to self :)
Ok, 2 things must go right to post a pic:
1) The pic must go where you want it to
2) The link to the pic must be correct in your post!
a) Just entering the path as:
...should put it in http://home.wanadoo.nl/gigajosh/pics where you want it.
b) But the path the Blogger gives you when you choose to place it inline may be wrong, so check it's also http://home.wanadoo.nl/gigajosh/pics/my_pic.jpg or whatever.
NOTE: You can always go to http://www2ftp.de for emergencies!
