Send Images to RSS vs WebP Express

Send Images to RSS bridges the gap between large websites and small emails, by replacing images in your feed with smaller, email friendly images, and attempting to add markup which email clients can handle. Between larger monitors, retina screens, and better image optimization, the images we serve up on our websites are larger than they’ve ever been. RSS to email services such as MailChimp, however, are constrained to what email clients can display, which is small, small, small. And although it’s possible to try to style images with a max-width in your emails, not all clients will honor it (I’m looking at you, Outlook). Send Images to RSS makes it easy to create beautiful, email friendly RSS campaigns, with minimal setup required, regardless of your feed setup. Full Text RSS Feeds If your site’s RSS feed is set to Full Text, this plugin makes sure your emails look more like your website: Replace overly large images with email friendly size images. Convert galleries from thumbnails to full width images. Add email friendly styling/alignment to your images. Summary Text Feeds If you’ve used Summaries as your RSS feed settings, this plugin has not been for you. Until now. As of 3.0.0, Send Images to RSS brings the awesome to you, too. Here’s the magic for your Summary feed: Add the post’s featured image to your excerpt. Choose the size and alignment. If no featured image is set, the plugin will use the first image uploaded to the post. Set a custom length for your RSS summary/excerpt. Pick the number of words you want your summary to have, and the plugin will aim for that, but with the added bonus of making sure the final sentence is complete. If you add a manual excerpt to your post, because you like to have full control, the plugin will properly use that instead. Automatically add a custom “read more” link to the end of every post summary, to keep your feed pointed back to your site. Known (non)Issues This plugin should work with any theme. Some themes and plugins do modify the feed for their own purposes. Where possible, I’ve tried to account for them: For summary feeds, the Yoast SEO RSS link is removed (the full text feed and front end output are not changed). For summary feeds, the excerpt filter added by the Woo Canvas theme is removed (the full text feed and front end output are not changed). For summary feeds, this plugin will replace the image settings for Display Featured Image for Genesis for versions 2.3.0 and later (because this plugin is smarter). If you’re using Display Featured Image for Genesis 2.2.2 or lower, this plugin will concede graciously. But you should update, please. For full text feeds, this plugin will not duplicate featured images if they are being added by Display Featured Image for Genesis–you will want to disable that feature in Display Featured Image for Genesis. NOTE: it is up to you to check that your feed output is still working, especially in your email system of choice, once it’s installed. I’ve attempted to set it up to handle XHTML or HTML5, and function even if your feed is wonky, but please double check, and let me know if you have issues, and if so, what specifically they are. Props Special thanks to Gretchen Louise for her summary feed contributions. Spanish translation offered by Web Hosting Hub

More than 9 out of 10 users are using a browser that is able to display webp images. Yet, on most websites, they are served jpeg images, which are typically double the size of webp images for a given quality. What a waste of bandwidth! This plugin was created to help remedy that situation. With little effort, WordPress admins can have their site serving autogenerated webp images to browsers that supports it, while still serving jpeg and png files to browsers that does not support webp. The image converter The plugin uses the WebP Convert library to convert images to webp. WebP Convert is able to convert images using multiple methods. There are the “local” conversion methods: imagick, cwebp, vips, gd. If none of these works on your host, there are the cloud alternatives: ewww (paid) or connecting to a WordPress site where you got WebP Express installed and you enabled the “web service” functionality. The “Serving webp to browsers that supports it” part. The plugin supports different ways of delivering webps to browsers that supports it: By routing jpeg/png images to the corresponding webp – or to the image converter if the image hasn’t been converted yet. By altering the HTML, replacing image tags with picture tags. Missing webps are auto generated upon visit. By altering the HTML, replacing image URLs so all points to webp. The replacements only being made for browsers that supports webp. Again, missing webps are auto generated upon visit. In combination with Cache Enabler, the same as above can be achieved, but with page caching. You can also deliver webp to all browsers and add the webpjs javascript, which provides webp support for browsers that doesn’t support webp natively. However, beware that the javascript doesn’t support srcset attributes, which is why I haven’t added that method to the plugin (yet). The plugin implements the “WebP On Demand” solution described here and builds on a bunch of open source libraries (all maintained by me): – WebP Convert: For converting images to webp – WebP Convert Cloud Service: For the Web Service functionality – DOM Util for WebP: For the Alter HTML functionality – Image MimeType Guesser: For detecting mime types of images. – HTAccess Capability Tester: For testing .htaccess capabilities in a given directory, using live tests – WebP Convert File Manager: For browsing conversions and triggering conversions. – Exec With Fallback: For emulating exec() on systems where it is disabled (using proc_open(), passthru() or similar alternatives). Benefits Much faster load time for images in browsers that supports webp. The converted images are typically less than half the size (for jpeg), while maintaining the same quality. Bear in mind that for most web sites, images are responsible for the largest part of the waiting time. Better user experience (whether performance goes from terrible to bad, or from good to impressive, it is a benefit). Better ranking in Google searches (performance is taken into account by Google). Less bandwidth consumption – makes a huge difference in the parts of the world where the internet is slow and costly (you know, ~80% of the world population lives under these circumstances). Currently ~97% of all traffic are done with browsers supporting webp. It’s great for the environment too! Reducing network traffic reduces electricity consumption which reduces CO2 emissions. Limitations The plugin should now work on Microsoft IIS server, but it has not been tested thoroughly. Supporting WebP Express Bread on the table don’t come for free, even though this plugin does, and always will. I enjoy developing this, and supporting you guys, but I kind of need the bread too. Please make it possible for me to continue wasting time on this plugin: Buy me a Coffee Buy me coffee on a regular basis and help ensuring my coffee supplies doesn’t run dry.
