web_lid

Bannerlid provides a simple WordPress admin extension to add banners and groups of banners to your WordPress template or your WordPress content. Banners can be added through content shortcodes or functions in your template files.
The plugin also tracks clicks and impressions and displays the data in html5 charts in wp-admin. Stats include who’s been clicking, when and where from.
Banners can be standard graphic file such as gif or png. It also supports flash banners, although these can cause speed and compatibility issues.
The plugin does not facilitate the selling of banners or banner space. I created this to be a simple Banner management system that provided clients with simplicity and important stats rather than to try and do too much.
The plugin comes with some basic filters and hook actions for customization.
