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)
