Add image captions
Add an image in this format:
![[image.jpg|This is a caption]]
or this format:

and it will add the caption underneath the image, like this:

Resize images
You can use the existing Obsidian width parameter to resize your images:
![[image.jpg|This is a caption|150]]
or this format:

Image alignment
You can center images or float them to the left and right, and resize also:
![[image.jpg|This is a caption|center]]
![[image.jpg|This is a caption|left]]
![[image.jpg|This is a caption|right|150]]
Markdown in captions
You can include inline Markdown and it will be rendered as part of the caption:
![[image.jpg|This is a caption with **bold text**]]
You can use Markdown links as normal:
]]
To use Wikilinks, you'll need to swap your square brackets [[]] for angle brackets <<>>:
![[image.jpg|This is a caption with <<a Wikilink>>]]
Use filename as caption
If you want to use the image filename as the caption, specify % as the sole text of your
caption, and it will replace that with the filename (without extension):
![[image.jpg|%]]
If you want to literally use the % character as the caption, you can escape it:
![[image.jpg|\%]]
If you want the filename including extension, use %.%.
Custom regex to filter caption
If you use other themes or plugins which require you to add data into the image description field, you can use a regex to remove those from the final caption. You will find this in the plugin Settings.
Two common examples would be from the ITS Theme, which lets you put |right etc to change the postion of your image.
To remove everything after the first pipe | character from your caption:
^([^|]+)
If you want to keep escaped pipes \| (in case you are using internal links), use:
^((\\\||[^|])+)
Styling
You can apply CSS styling by targeting the .image-captions-figure and .image-captions-caption classes.
Limitations
External images won't show the caption in Editing / Live Preview mode. For example:

I couldn't find a reliable way of targeting them. Get in touch if you know a way to do this!
Internal images are fine.
