This wordpress plugin allows visitors to browse posts or pages by their images, displayed randomly on an infinitely scrollable Image Wall. The images link back to the post or page on which they are attached.
Images are powerful. They catch our attention like nothing else. You probably use them in your blog posts to anchor the fickle attention span of today’s readers. Display all these great images on a nice looking page, and your visitors will browse for a while, captivated. Hopefully, one image will stand out for whatever reason and compel the visitor to click it to find out more. And just like that, some old blog post you thought buried by the sands of time has gotten another view, thanks to your Image Wall.
You can see the plugin in action on my own <a href="http://www.themodernnomad.com/image-wall/#utm_campaign=Image_Wall&utm_source=wordpress&utm_medium=website&utm_content=description" rel="nofollow ugc">Image Wall</a> and the full plugin documentation on the <a href="http://www.themodernnomad.com/image-wall-plugin/#utm_campaign=Image_Wall&utm_source=wordpress&utm_medium=website&utm_content=description" rel="nofollow ugc">Image Wall Plugin page</a>.
