How to customize previous and next links with graphic

Depends on your theme. For instance If it has an archive.php
should be lines that inlude:
next_posts_link
previous_posts_link

And you can just ad img tags for them. so for previous posts it should look something like:
previous_posts_link(‘<img src=https://webjunk.com/prev-img.jpg>’, 0)

Thanks,
Using wp-framework archive.php is pulling in navigation.php not sure what to change on this page. This is the code on navigation.php
<?php
/**
* Template: Navigation.php
*
* @package WPFramework
* @subpackage Template
*/

if ( is_singular() and !is_page() ) { ?>
<!–BEGIN .navigation-links–>
<div class=”navigation-links single-page-navigation”>
<div class=”nav-previous”><?php previous_post_link( ‘<span class=”nav-meta”>%link</span>’ ); ?></div>
<div class=”nav-next”><?php next_post_link(‘%link <span class=”nav-meta”>»</span>’); ?></div>
<!–END .navigation-links–>
</div>
<?php } else { ?>
<!–BEGIN .navigation-links–>
<div class=”navigation-links page-navigation”>
<span class=”nav-next”><?php next_posts_link( ‘<span class=”nav-meta”>«</span> Older Entries’ ); ?></span>
<span class=”nav-previous”><?php previous_posts_link( ‘Newer Entries <span class=”nav-meta”>»</span>’ ); ?></span>
<!–END .navigation-links–>
</div>
<?php } ?>

Maybe change the section of your code to:

<span class="nav-next"><?php next_posts_link( '<img src=https://webjunk.com/prev-img.jpg>' ); ?></span>
<span class="nav-previous"><?php previous_posts_link( '<img src=https://webjunk.com/prev-img.jpg>' ); ?></span>

Thanks, I just got that part to work. This is section I’m having trouble with now.

<div class=”nav-previous”><?php previous_post_link( ‘<span class=”nav-meta”>%link</span>’ ); ?></div>
<div class=”nav-next”><?php next_post_link(‘%link <span class=”nav-meta”>?</span>’); ?></div>

I converted to:
<div class=”nav-previous”><?php previous_post_link( ‘<img src=”https://woo-atlanta.com/clients/femme-brunette/wp-content/themes/femme_brunette/images/previous.jpg&#8221; />’ ) ; ?></div>
<div class=”nav-next”><?php next_post_link( ‘<img src=”https://woo-atlanta.com/clients/femme-brunette/wp-content/themes/femme_brunette/images/next_arrow.jpg&#8221; />’ ) ; ?></div>

And it doesn’t work. Images show up but don’t link.

Here is what the code looks like now.

<?php
/**
* Template: Navigation.php
*
* @package WPFramework
* @subpackage Template
*/

if ( is_singular() and !is_page() ) { ?>
<!–BEGIN .navigation-links–>
<div class=”navigation-links single-page-navigation”>
<div class=”nav-previous”><?php previous_post_link( ‘<img src=”https://woo-atlanta.com/clients/femme-brunette/wp-content/themes/femme_brunette/images/previous.jpg&#8221; />’ ) ; ?></div>
<div class=”nav-next”><?php next_post_link( ‘<img src=”https://woo-atlanta.com/clients/femme-brunette/wp-content/themes/femme_brunette/images/next_arrow.jpg&#8221; />’ ) ; ?></div>
<!–END .navigation-links–>
</div>
<?php } else { ?>
<!–BEGIN .navigation-links–>
<div class=”navigation-links page-navigation”>
<span class=”nav-next”><?php next_posts_link( ‘<img src=”https://woo-atlanta.com/clients/femme-brunette/wp-content/themes/femme_brunette/images/previous.jpg&#8221; />’ ); ?></span>
<span class=”nav-previous”><?php previous_posts_link( ‘<img src=”https://woo-atlanta.com/clients/femme-brunette/wp-content/themes/femme_brunette/images/next_arrow.jpg&#8221; />’ ); ?></span>
<!–END .navigation-links–>
</div>
<?php } ?>

I can’t seem to get it to all work together.

You gave two different replies so don’t know what I am replying to. The first reply you missed the:
%linkwhen you added the images.
