Hi, You can do that all by adding template override actually. Please follow this video if you don't know how to do that https://www.youtube.com/watch?v=tMB97xfYQfY

and for your questions :

1) How can I get the article title to link to the assigned link in the "Images and Links" settings of the Article instead of the article details?

Did you mean you want to use Link A, Link B, Link C instead of single article link?

if so, you can add this code in your template override :

<?php $articleLinks = json_decode($item->urls); echo "<a href="/.$articleLinks->urla.">Link A</a>"; ?>

2) Is it possible to show html (small image w/ link) in the Intro Text? - It shows in the details page but not the intro text (and it is within the intro chars limit)

after you have created template override, find this part :

echo JHtmlString::truncate(strip_tags($item->introtext), $introtext_truncate); 

change that to

echo $item->introtext; 

For #1 - can I add <?php $articleLinks = json_decode($item->urls); echo "<a href="/.$articleLinks->urla.">Link A</a>"; ?> anywhere in the override code?

You can add that code anywhere inside the loop (foreach ($list as $item) : )

anyway you can give me an approximate code line # so I'm in the right area?

You can put it at lines 207

it will show the link after the introtext

hmmmm...it throws an error when I put in that code so I'm obviously doing something wrong.

Can you tell me what theme do you use?

Default w/ card.min skin

what error message did you get

blank white screen w/ "error" in top left corner
