This plugin hasnt been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.
I found out your plugin/module is not updated anymore but still working on the latest core version of wordpress. This plugin is very helpful and unique. Hope to update and maintain this plugin. Thank you.
I use this to add marker coordinates to a simple world map image. works great with repeater field. only "problem" is it saves the percentages as a string separated by comma and with a lot of decimals. so first thing to do is to explode the string in order to access the left and top percentages.
