Dear @rimusport, I guess the screenshot is from the deck app, right? Text doesn't support inline attachments/images there. That's also why adding attachments in the editor lists the attachments for the deck card instead and doesn't allow to inline them.

I guess that you added some markdown syntax that referenced an image? How did you come to this result?

Technical background: The limitation is because the editor content is not bound to a markdown file (with a corresponding file ID) in deck. And that would be required to have an attachments folder.

I have the same problem. Yes its the deck app. Reproduce:
-open any card in deck
-click on the "attach files" icon
-upload image from computer
-click on small arrow behind the file name to choose/insert that image

I have the same issue when I try to link an image in the description of a Deck card, whether by "insert attachment", or by linking an external image by raw Markdown code, i.e.:

![](https://example.com/example.jpg)

@mejo- I am trying to insert a card cover image, which should be possible from what I understand. If this is the wrong way, what is the correct way to insert/link an image to show as cover image?

hasn't worked for us in about 3 versions... we do not use it much (occasional joke pic here and there)

The editor in Deck app doesn't support to upload attachments. Nowadays the UI elements to do so are also disabled, so I'll close this usse.

@mejo- I understand the perspective.
However, there are a lot of old cards that still have images in the description.
And if Nextcloud Text is disabled temporarily, attachments can still be uploaded into the description, which will then not show up when Nextcloud Text gets reenabled.

Was there an official decision and switch, to disable uploading attachments to Deck card descriptions and disabling the feature? And why?
If yes, then the upload feature in Deck without Nextcloud Text should also be removed.

Do you have any insight on why the error is happening? It would be great to just fix it.

I see the argument that this is a regression, so let's reopen the issue. @grnd-alt @elzody what do you think?
