Image Quality

I’ve worked around this to some degree but results can be inconsistent – after the plugin generates TERRIBLE-looking images (at least for vector-heavy stuff, images are OK), THEN I go into the server FTP and manually upload better images. The other images that the plugin generates aren’t visible in the WP media browser.

Interesting. I was having a similar issue and briefly delved into the subject of responsive/adaptive images. WordPress has contained this feature since 4.4.

My proposal to Lee is to augment SEO Slider to serve responsive images using the WordPress-provided srcset method, or at least publish a filter that would allow us to opt into that functionality.

@mafreprezent (cool username) — can you link up a Gist with your workaround?

@mafreprezent The plugin adds a new image size called ‘slider’. It’s set to 1280 x 720 and is only used as the slider background image, the plugin was intended for creating full-width hero sliders as seen in the Corporate Pro demo.

@hifidesign Great suggestion. I’ll add that in the next update.

@seothemes I understand it creates a new image size, and when it does, the image sucks (if it’s a vector). And to be clear, that’s true on both the slider and with hero images on subpages within the Corporate Pro theme (made by SEO Themes). Sorry for lumping them together, it’s just the slider is bundled with the theme.

@hifidesign My workaround is simply bypassing WP and replacing the images on the server FTP manually by making copies of better images and renaming them in the convention of the image size (image-name-1280×720.png). I don’t have a coded solution for automating that, but it seems like it would be a fun Python project ??

@mafreprezent @hifidesign There is actually a filter already available in the plugin – seo_slider_image_size. You can change with the following code:

add_filter('seo_slider_image_size', function() {
	return 'full';
});

@seothemes Whoa, thanks for the wizardry, thanks SEO themes! I guess I should give this plugin an awesome rating ??

@mafreprezent no problem at all. Thanks for the review!
