Is there a way to show a 1px border around images attached in posts (with ILA addon)?
I think that should be easy though I haven't tried.
Something like this is working in a custom.css:
.bbc_img {
border: 5px solid green;
border-radius: 8px;
}But than
every inserted image in the post will get a border, also for example a little smiley from another server. Looks funny. ;)
I'm not sure it's the best solution, I wanted to change the max-width of images inserted with attachimg code from ILA for Elkarte 1.0.x and I did it directly on ILA.subs.php file. You can find an example here https://www.elkarte.net/community/index.php?topic=1450.msg19660#msg19660
In the same way you can add a border to inline images inserted with attachimg or attach bbcode
And that can even be extended to a more "enhanced" ILA css style setting, if its author wants.
