I'm wondering if I'm wrong in adding the image size filter to my theme's functions.php file to config featured image size display. Is there another place to add the filter and, if so, where and what is the syntax exactly for a 575w x 350h image?
When I enter the filter in the functions.php file, the full size image displays only. I've tried both the width,height array method as well as medium, large etc. instead of the array. It always shows the full size image regardless.
Example in STUDENT VOICES section near bottom here: http://gse.zdca.biz
The large image that exceeds the layout seems to also remove the testimonial text entirely too. If I comment out the filter in the functions.php file, everything works except the image is the thumbnail size (which I don't want).
What I've tried in the functions.php that both produce the same broken result:
add_filter( 'testimonials_widget_image_size', array( 575, 350 ) );
add_filter( 'testimonials_widget_image_size', medium );
Any help is much appreciated, thanks!
