I'm using get_the_image when showing post excerpts as follows:
get_the_image(array( 'image_scan' => true , 'image_class' => 'excerpt-thumbnail','width' => 150 , 'height' => 150));
When my post has a featured image or the image is attached it's showing the 150x150 version of the images.
However when it's falling back on the scan it's showing a large image and resizing it in the browser to 150x150 rather than using the available thumbnail. The particular image is attached to a different page hence does not attached to this post when I insert it from the gallery.
Is there any way I can get it to check for thumbnails in this situation?
