<?php echo get_avatar($id_or_email, 50, $default_avatar ); ?>
1. According to the codex, to change the default avatar I would use $default = ‘<path_to_url>’ as the last parameter. How do I make a relative call to an image inside <?php ?>. I’d like to do it similarly to how I call images –
<img src="<?php bloginfo('stylesheet_directory'); ?>/img/someimage.jpg" alt="alt text here" />
2. How can I add alt text using the get_avatar function?
3. How can I link the gravatar image?
Thanks for any help you can provide.
