Well, I manaded to get a new picture on the blogg. But not quite the way I would have loked to do it: it only appears to be on the blogg, but it is in reality hosted somewhere entirely different. Granted, I own the server the picture is on, but it feels ever so slightly wrong transfering the picture to my server, and then linking to it from inside WordPress.
Ah well, it works at least. But whether or not my uploading problems persist remains to be seen, as does whether or not I will keep on blogging here if I must host the pictures somewhere else.
