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.
Install just like most other plugins. Download or Install it first then active it. its so simple to manage.
