Question

I'm using Drupal 7 and Field Slideshow plugin. I published my slide and working. It's have a pager and that's name 'Prev' and 'Next'

I don't want text, must image. How can i do it?

<div id="field-slideshow-<?php print $slideshow_id; ?>-controls" class="field-slideshow-controls">
  <a href="#" class="prev"><?php print t('Prev'); ?></a>
  <?php if (!empty($controls_pause)) : ?>
    <a href="#" class="play"><?php print t('Play'); ?></a>
    <a href="#" class="pause"><?php print t('Pause'); ?></a>
  <?php endif; ?>
  <a href="#" class="next"><?php print t('Next'); ?></a>
</div>

Answer 1

<div id="field-slideshow-<?php print $slideshow_id; ?>-controls" class="field-slideshow-controls">
  <a href="#" class="prev"></a>
  <?php if (!empty($controls_pause)) : ?>
    <a href="#" class="play"><?php print t('Play'); ?></a>
    <a href="#" class="pause"><?php print t('Pause'); ?></a>
  <?php endif; ?>
  <a href="#" class="next"></a>
</div>

And styles like this:

.prev {
    display:inline-block;
    width:20px;
    height:20px;
    background: transparent url('path/to/prev/image.png') no-repeat center center;
}

.next {
    display:inline-block;
    width:20px;
    height:20px;
    background: transparent url('path/to/next/image.png') no-repeat center center;
}

Or you can have something like this:

<div id="field-slideshow-<?php print $slideshow_id; ?>-controls" class="field-slideshow-controls">
      <a href="#" class="prev"><img scr="path/to/prev/image.png" alt="<?php print t('Prev'); ?>" /></a>
      <?php if (!empty($controls_pause)) : ?>
        <a href="#" class="play"><?php print t('Play'); ?></a>
        <a href="#" class="pause"><?php print t('Pause'); ?></a>
      <?php endif; ?>
      <a href="#" class="next"><img scr="path/to/next/image.png" alt="<?php print t('Next'); ?>"  /></a>
    </div>
