We updated the Image credits Bildquellen and they are working again, and in perfect conditions.
When you upload an image, fill in the Bildquelle fields (both has to be filled for it to appear).
Your blog post will automatically visualize the image credits, when it is published. (See below.)
You might notice the new author interface which came with the new wordpress update. WordPress 3.8 brings a fresh new look to the entire admin dashboard. Gone are overbearing gradients and dozens of shades of grey — bring on a bigger, bolder, more colorful design! It works perfectly on smartphone, tablet, notebook, or desktop – no matter what you use.
Blog users can individually customize their favorite color scheme from the Profile / Benutzer panel.
