Afaik there’s no plugin which allows you to set the featured image automatically because it doesn’t make sense in most cases.

WordPress just saves the id of the (full size) image when you set an image as “post thumbnail”. This id will be used to query the url path to the full size image OR to a thumbnail of this image (depends on the theme code).

If you already uploaded “high resolution” images and set these images as post thumbnails you just need to regenerate the thumbnails with: http://wordpress.org/plugins/regenerate-thumbnails/

Afterwards wordpress will use the proper thumbnail size of these images for the post thumbnails. If you want to change the thumbnail size open up and search for /wp-content/themes/enfold/includes/loop-index.php

$current_post['slider']  	= get_the_post_thumbnail($the_id, $size);

Replace the $size variable with any custom value like

$current_post['slider']  	= get_the_post_thumbnail($the_id, 'full');

or

$current_post['slider']  	= get_the_post_thumbnail($the_id, 'large');

or any other thumbnail size which is defined in functions.php or which you created with http://wordpress.org/extend/plugins/simple-image-sizes/

Hi!

Try following – open up wp-contentthemesenfoldconfig-templatebuilderavia-shortcodesslideshow.php and replace

$link	 = wp_get_attachment_image_src($slide->ID, 'large');

with

$link	 = wp_get_attachment_image_src($slide->ID, 'full');

Best regards,

Peter

The difference is that the image sliders and the post sliders do not support custom content. The image slider can just display images with captions, the post slider can display posts. The content slider allows you to slide any text or content (including shortcodes) – many users requested this feature and thus we decided to implement it.

2) No, you can’t hide the space by default. If you want to hide it open up wp-contentthemesenfoldconfig-templatebuilderavia-shortcodescontentslider.php and replace

$output .= "<div class='avia-smallarrow-slider-heading'>";

$output .= "<div class='new-special-heading'>".$heading."</div>";

with

$heading_class = '';

if($navigation == 'no') $heading_class .= ' no-content-slider-navigation ';

if($heading == ' ') $heading_class .= ' no-content-slider-heading ';



$output .= "<div class='avia-smallarrow-slider-heading $heading_class'>";

$output .= "<div class='new-special-heading'>".$heading."</div>";

The use following css code to hide the space if no title & control buttons are set

.no-content-slider-navigation.no-content-slider-heading{

display: none;

}

Go to GTMetrix.com and run your URL through it. Then Install the free wordpress plugin ‘W3 Total cache’ and set it up as explained here: http://gtmetrix.com/wordpress-optimization-guide.html (you can also optimise your images with ‘WP Smush’ as explained in this link)

Then retest your site at GTMetrix and see the improvement!
