Can you tell me how to change alignleft to alignright in function themedemo_entry_image() ?
i tried "'attr' => genesis_parse_attr( 'entry-image', array ( 'alt' => get_the_title() , 'class' => 'alignright post-image' . $cat_class ) ),"
but alignleft is still in attr.

I don't know what the inline instruction 'Replace all instances of "themedemo" with something unique to your site.' is supposed to mean. Can someone please elaborate

@rgoldston - it's not necessary, those are the function names, and they can remain that way if you don't want to bother. He's just suggesting that those names should probably be something more specific to your site, or something that means more to you (maybe a reminder that those functions came from this page, or something you didn't write). It's a suggestion rather than a requirement.

[Update: Argh, nevermind. ARIA was just not working in my browser. Fixed.]

Is there any way to put a display:none in the image tag that it outputs after the <a href="%s" aria-hidden="true">%s</a> bit?

The reason being twofold.

1. Styling the Entry-Image is a little easier if I can make my own CSS-classed div
2. Sometimes, the entry has both a Video in the excerpt and a still-image that functions as the official Featured Image for the post.

The way it is in the code puts the image in-addition to the ones I already manually-declared at the beginning of both the entry & excerpt.

Any help would be appreciated! -Thx.
