It appears that the dev team broke out all the functions and didn’t realize that the short code was affected when they created “youtube-channel-gallery/templates/thumb.php” The variable that is set for the “width” for the WIDGET, is the killer for the SHORTCODE issue (from what I’ve found).
I made the following update and it appears the Shortcode thumbnail size is fixed for me.
Goto PLUGINS > EDITOR and select “Youtube Channel Gallery” from the drop down. then select “youtube-channel-gallery/templates/thumb.php” .
from there replace: $ytchag_thumb_width with $ytchag_thumbnail_fixed_witdh
Test!
basically it was pulling the wrong value and defaults to the assigned width for the video player.
