Regenerate Thumbnails
Regenerate Thumbnails allows you to regenerate the thumbnails for your image attachments. This is very handy if you’ve changed any of your thumbnail dimensions (via Settings -> Media) after previously uploading images or have changed to a theme with different featured post image dimensions.
RICG Responsive Images
This plugin works by including all available image sizes for each image upload. Whenever WordPress outputs the image through the media uploader, or whenever a featured image is generated, those sizes will be included in the image tag via the srcset attribute.
RSS Image Feed
The RSS Image Feed doesn’t create a feed of images, but attaches the first image of the post to your feeds. Normally only the content has images showing. With our plugin there will be a clickable image even in the excerpt and in the content there will be only one image instead of all the images of the post. Since version 2.2 it works as a multisite plugin as well.
Joe, you provide some outstanding information.
However, the real truth is that plugins (themes, or templates) are often not the biggest problem for most WordPress users. They want to get traffic, they want an online business. Keep adding or changing plugins, themes and other features does not solve their real problem. WordPress “as is” won’t build an online business. It’s missing a do-able start-to-finish BUSINESS process.
Surely, you can slog through the mountains of business building advice and tools that are out there. But for most WordPress users it all ends up being too much.
So, despite the dazzling display of WordPress features, the reality for most (non-tech) people who want to create a web business with WordPress is that they need to adhere to an easy-to-follow, all-in-one, proven, ethical webbusiness-building system (not a get rich quick scheme), tailored to the WordPress platform, to get (1) a significant amount of traffic and get (2) targeted traffic (example of such a system: WealthPrinciples dot net).
Otherwise you’ll end up having (and building) only a WordPress webSITE (or BLOG) but not a webBUSINESS.
