Describe the Bug

In version 2.0.0 I have the images with content (I use backticks in the real version but use ::: here for formatting reasons), e.g.:

:::{image} /_static/blog_images/neuroblueprint/NeuroBlueprint_project_tree_dark.png
   :align: center
   :class: only-dark
   :width: 650px
:::

:::{image} /_static/blog_images/neuroblueprint/NeuroBlueprint_project_tree_light.png
   :align: center
   :class: only-light
   :width: 650px
:::

but the content is not respected (e.g. image size) and the warning reads:

16: WARNING: 'image': Has content, but none permitted [myst.directive_parse]

I checked the changelog and couldnt see anything immediately relevant so listed as bug, but maybe this is a new feature I am misunderstanding.

Expected Behavior

Image formats with content as directed .

To Reproduce

I believe building with any image content should show the error.

Heya, ah I think I know why this is, if you have the options without the indentation, it should work, e.g.

```{image} /_static/blog_images/neuroblueprint/NeuroBlueprint_project_tree_light.png
:align: center
:class: only-light
:width: 650px

let me know?

But yeh I can fix this regression (and add a test to catch it 😅) hopefully in the next day or two

[JoeZiminski]

Thanks for the quick response @chrisjsewell, that fixed it!! 😄 Cheers

[chrisjsewell]

Cheers, yeh one of those things where an "implementation detail" becomes part of the spec lol; I must have removed the lstrip when checking if a line is part of the option block, but didn't account for this possibility of having indented options.

I use backticks in the real version but use ::: here for formatting reasons

FYI you know you can just surround with more backticks, e.g.

``````outer
````inner
```more-inner
content

Thank you! We're seeing the same issue, with lots of warnings for all the indented options ...
