    I used your agnosia plugin – then wound up basically rewriting it.

    Thought I would return the favor by sharing the revamped code with you.

    note:
    instead of hijacking the gallery hook, this is actually a new shortcode.

    so instead of [gallery type="carousel" ids="1,2,3,4"]
    you’d use [bootstrap_carousel ids=”1,2,3,4″]

    there’s still a simple substitution but this way the gallery hook is not tampered with. (Wouldn’t work if someone else tried to do the same thing the same way)

    Hi, Steven. Thank you very much for your feedback!

    I’ll study your code and see if I can add some of it in the next version of the plugin.

    Cheers, and thanks a lot again.
