Ok..so this is the second post because everyone is ignoring the first one.
here is the code I need to work with:
<?php echo get_post_image (get_the_id(), '', '', '' .get_bloginfo('template_url') .'/scripts/timthumb.php?zc=1&w=260&h=230&src='); ?>
Now this is on the homepage, it leaves the alt tag blank. I have tried everything I know of to change this. I have tried modifying the function.php file (I can set a generalized alt tag there which is a temporary measure), I have tried adding in
alt="<?php the_title(); ?>" and it does not work.
Someone please help me. I think everyone that uses the Mimbo theme would love to have this SEO option to improve their search rankings.
