Single Image Widget Plugin
Single Image Widget to add any images to your sidebars.
single image Widget is what the name implies — the easiest way to add images to your sidebars. Display advertisements, calls-to-action, or even build a slider based on image widgets.
Despite its simplicity, single image Widget is built with extensibility in mind, making it super easy to spin off new image-based widgets, or customize the widget ouput using the available template hierarchy.
