iFrame-less Reloaded plugin is a simple and SEO friendly way to embed non-PHP dynamic content directly onto a wordpress page.
Based on the IFrame-less plugin by Fiach Reid (https://profiles.wordpress.org/users/freebiesms/) but extended to allow multiple widgets per sidebar.
Original Desc taken from IFrame-less : Not everyone who uses wordpress knows PHP. Perhaps you are more familiar with ASP.NET or JSP,but you can not just put ASP.NET or JSP code in the middle of wordpress, especially if your server does not support it.
Using an IFrame is a possibility, but it has some SEO (Search Engine Optimization) downsides, since, search engines will view that content as part of another page, and give your blog no extra credit for this content.
This plugin allows you to specify a URL, which this plugin will fetch for you, and re-display on the page, as part of the page content. Giving you the SEO advantage that an IFrame looses.
Note, this plugin should only be used to import content which you own or have rights to display on your site

This basic plugin adds the Magnific Popup lightbox script to wordpress site and works with single images, iframe links and dialogs.
All you need to do to use Magnific Popup on a link is to add specific css class to ‘a’ tag. CSS class names can be configured on settings page.
For images you can use alt attribute to add captions.
