Using Custom Image Sizes

The banner image size is maxed out at 2000 pixels, so even if someone uploads a ginormous image, the plugin is still doing everything it can to protect a user from him/herself. I can look into adding a filter to modify the registered image size, or possibly changing which registered image size the plugin uses, although it’s going to have limited usefulness, I think, due to the nature of the calculations the plugin performs behind the scenes. But I should be able to incorporate that in the next release.

If you’re still wanting to tinker with this, you can download the latest develop branch of the plugin from Github and use this new filter: displayfeaturedimagegenesis_image_size, which is in the Common class. You just need to return the name of the image size you prefer to use. Just know that the plugin will still do its measurements, etc. as it determines how to handle the output. This will be in the next version, but I’m not ready to ship that yet, so the develop branch is your best bet if you want it now.

Hey Robin, I downloaded the development branch and installed and I can’t get the featured image to display at all. Here’s the code I tried:

add_filter( 'displayfeaturedimagegenesis_image_size', 'rgc_set_image_size' );
function rgc_set_image_size ( $imagesize ) {
	$imagesize = 'my-image-size';
	return $imagesize;
}

add_filter( 'display_featured_image_genesis_use_large_image', 'rgc_use_large_image' );
function rgc_use_large_image( $post_types ) {
    $post_types[] = 'post';
    $post_types[] = 'page';

    return $post_types;
}

I also tried with just the 2nd function (which works with the production plugin but not development). Thoughts?

The two filters you posted are applied in the same function. I’ve fixed a bug which erroneously allowed the first one ('displayfeaturedimagegenesis_image_size') to override the second.

I created a custom image size on my development site called 'my-image-size', used the filter above, and created a new post and uploaded a new image (note that in order for previously uploaded images to use the new image size, you need to run a plugin like Regenerate Thumbnails). The plugin correctly used the new custom image at the new size. Can you double check it, please, maybe with a new image?

If you have a link you can share, I can try to look at it, but may not be able to tell much from the front end. But if you can update to the latest commit (the only file changed is the Common class), see if that helps.

Robin, it’s showing the image again with the newest development build but no matter what “image size” I use in the code, it displays the same size image.

add_filter( 'displayfeaturedimagegenesis_image_size', 'rgc_set_image_size' );
function rgc_set_image_size ( $imagesize ) {
	$imagesize = 'featured-image';
	return $imagesize;
}

I’ve tried three different image sizes, including this small one above, and a large image is still displaying on the page. I also deleted and re-uploaded the image just to be safe.

This is a brand new site with almost no plugins, so I don’t know why it wouldn’t be working. Happy to send you the URL to look at but I can’t post it publicly as it’s for a client. Is there an email address I can send it to?

If you use a small (enough) image, the plugin shouldn’t be able to output at all, due to the calculations it goes through. (I swapped out medium for your ‘featured-image’ and the plugin wouldn’t output, which is what I would expect.)

Yes, if you can share the link privately with me, I would like to look into this in more detail. You can shoot me an email from my contact page on my site.

If you can also confirm how you are adding your custom image size (in the email is fine) to your site, and confirm that the correct copy of the image has been created, that would be awesome. Thanks.
