I have sent an initial patch to the digikam developers for supporting 23hq. They have done some more tweaks to it and some more work to it. Now it’s in their CVS and it works flawlessly. So, if you are using 23hq and digikam as your photo management software you can upload your pictures directly from digikam to 23hq now. 😀
Thanks to Luka Renko who has done the work after my initial patch.
