Is there a way to add a class to the img tag that would then allow me to easily add this optionally? For example, if I could do something like:
\
Then I could be able to really easily add the custom CSS to add borders just to that class.

I guess you could just add this manually, right? (Both in your post and in your CSS customizations. I haven’t tried.)
If it works then maybe something simple like a check box for borders in the upload UI could do the same thing?

I tried adding it to the post manually and it seems to get stripped out…

Two screenshots…one of the above post in edit mode…
So you can see that I’ve added a class to the tag.
Then another screenshot of me doing inspect element where the class is gone from the tag:
I’m sure this is intentional, but not sure if there’s a way to workaround it.

We are having the same issue. Can you guys confirm there is a bug? We were able to add custom classes to images before but now when we create a new topic it is removed.

There is a new MarkDown editor and I think it only allows certain tags and attributes…
`class` may not be one of them and may be stripped.
If you just want a border on all your included images, what’s wrong with:
```plaintext
.cooked img {
border: go-wild;
}
```
or something similar? But of course, you’ve got to handle the emoji’s.

This was recently changed:

As there wasn’t a restriction on classes, it would have been possible to do something like this:
