# Have an alternative text but no caption or a different caption in bookdown::git_book

In an `bookdown::git_book` I'd like to

• have alternative text for figures (`alt`), but no caption
• or even have an alternative text that's different from the caption.

At the moment it seems both are controlled by the chunk parameter `fig.cap`.

To disable figure captions in the whole document, the `fig_caption` config param didn't work so I resorted to CSS in this minimal example with @rlesur's help.

I have two related questions:

• Is there a better way to disable figure captions in the whole book?
• Could one have captions that are different from the alternative text?

I'm sorry if I missed a previous question / issue about this and welcome any insight.

sounds like you already used:

``````fig_caption: false
``````

in the markdown header options?
I understand you want to disable figure captions throughout the whole book, but the only other option I found at the moment is to put a "\" at the end of the image chunk, eg.

``````![my caption](C:/mypath/myimage.png)\
``````

let me know if this is still an issue and I can try again

Thanks, yes the option didn't work.

I saw that trick with the backslash too but my images are generated by R, so I'd need to edit the plot hook.

I've opened an issue in `bookdown` repo itself.
