Hi,
I have similar problem. I want to show only 2logos. I have a solution, whcih works for 1, 2 or what number of logos you want.
1) Edit file: logo-slider/logo-slider.php (via FTP or in WordPress via Edit link)
In this file find this code (it is in middle):
<select name="wp_logo_slider_settings[num_img]">
<option value="3" <?php echo ($options['num_img'] == '3' ? 'selected="selected"' : '') ?>><?php _e('3','lgs') ?></option>
<option value="4" <?php echo ($options['num_img'] == '4' ? 'selected="selected"' : '') ?>><?php _e('4','lgs') ?></option>
<option value="5" <?php echo ($options['num_img'] == '5' ? 'selected="selected"' : '') ?>><?php _e('5','lgs') ?></option>
<option value="6" <?php echo ($options['num_img'] == '6' ? 'selected="selected"' : '') ?>><?php _e('6','lgs') ?></option>
<option value="7" <?php echo ($options['num_img'] == '7' ? 'selected="selected"' : '') ?>><?php _e('7','lgs') ?></option>
<option value="8" <?php echo ($options['num_img'] == '8' ? 'selected="selected"' : '') ?>><?php _e('8','lgs') ?></option>
</select>
And as you can see, there are listed all number options. So if you want add 1 logo option just insert this:
<option value="1" <?php echo ($options['num_img'] == '1' ? 'selected="selected"' : '') ?>><?php _e('1','lgs') ?></option>
under:
<select name="wp_logo_slider_settings[num_img]">
2) Go to plugin settings and change number of logos to 1! ??
The final code will look like this:
<select name="wp_logo_slider_settings[num_img]">
<option value="1" <?php echo ($options['num_img'] == '1' ? 'selected="selected"' : '') ?>><?php _e('1','lgs') ?></option>
<option value="3" <?php echo ($options['num_img'] == '3' ? 'selected="selected"' : '') ?>><?php _e('3','lgs') ?></option>
<option value="4" <?php echo ($options['num_img'] == '4' ? 'selected="selected"' : '') ?>><?php _e('4','lgs') ?></option>
<option value="5" <?php echo ($options['num_img'] == '5' ? 'selected="selected"' : '') ?>><?php _e('5','lgs') ?></option>
<option value="6" <?php echo ($options['num_img'] == '6' ? 'selected="selected"' : '') ?>><?php _e('6','lgs') ?></option>
<option value="7" <?php echo ($options['num_img'] == '7' ? 'selected="selected"' : '') ?>><?php _e('7','lgs') ?></option>
<option value="8" <?php echo ($options['num_img'] == '8' ? 'selected="selected"' : '') ?>><?php _e('8','lgs') ?></option>
</select>
