[Bug] Some images cannot be pasted into Anki’s Editor

Some images cannot be pasted into Anki’s Editor, although they can be pasted correctly in any other software.

The issue is clearly reproducible with Wiktionary and Wikipedia off-line files from the Kiwix Project.

Steps to Reproduce:

  1. Download a Wikipedia or Wiktionary in .zim format from the “Kiwix Project”. For example, the German Wiktionary (full version):


  1. Load the “Wiktionary” (.zim file) into GoldenDict-ng.
    Menu > Edit > Dictionaries > Sources (folder where the Wikipedia file is located)

  1. Once the “Wiktionary” is loaded, search a word containing an image. For example:
  • Australien
  • Karies
  • Leberwurst

  1. Right click on any image within GoldenDict-ng (Wiktionary in .zim format) and copy it to the clipboard.
  2. Paste the image in the Anki Editor.
  3. See the error: the image cannot be pasted into the Editor.

The editor fails to paste the image, although the same image can be pasted into any other program. For example:

  • CopyQ (Clipboard manager)
  • The native KDE Clipboard manager
  • Pinta
  • Krita
  • VocabSieve (Sentence Mining with Anki)

Only Anki fails to “accept” an image that is taken is clearly in the clipboard manager.

Expected behaviour:
Images from the clipboard manager should be pasted normally in Anki

This issue has been ocurring for many months. I have reproduced it across different distros in Linux and different versions of Anki. The problem persists without Anki Add-ons.

I guess that @abdo could easily reproduce this issue related to “GoldenDict-ng”. I remember that you know about GoldenDict and the 380 GiB collection of dictionaries at “FreeMDict Forum”.

Could you please try to reproduce this bug ? @abdo :pray:

GoldenDict apparently uses a custom URL protocol for images:

Anki is not recognizing this as a URL so it’s not trying to download it. I added a trivial fix to make it recognize the bres:// protocol but the download then fails with this error:

Interestingly, if you have the Paste Images As WebP add-on installed, the issue goes away. I’ll look into what’s the add-on is doing here to make it work.

Thanks for your hard work Abdo! :smiley:

I hope “dae” would agree to merge the commit.

This commit was reversed on GitHub by “dae” because it unexpectedly caused other issues:

I wonder if we could find a solution on “GoldenDict-ng” by Xiaoyifang ?

There are not so many users of GoldenDict in comparison with Anki. Therefore, this might be better to fix on the side of the dictionary software.

Maybe the simplest solution to suggest to the author is to make GoldenDict only write image data to the clipboard, with no HTML.

The Author of GoldenDict-ng argues that the problem is an Anki’s issue…

I also believe so because copying images from GoldenDict to other software programs work.

Only Anki has a small problem in the way it handles those images. This issue might be worth considering in the future to improve Anki…

Thanks for your hard work @abdo
