Okay, getting somewhere. Under the functions.php, the lines you posted above declaring the thumbnail dimensions. I’ve changed the true to false like so:
add_image_size('azulsilver-medium-thumbnail', 650, 150, false);
That’s resulted in the image being displayed in full (auto resized), gonna try some CSS to get the images to the size I want them.
Out of curiosity, what does the true/false part of the statement declare? I’m no where near as advanced at php as some people so it’s all a learning experience.
