No, the popup image does not use any special kind of positioning. The requirements for skinning the datepicker, so that there is space between the textbox and the image are:
1. Add right padding to the table cell, which contains the textbox (as suggested in my previous post)
2. The right padding of the textbox itself should be zero and the right border should be 1px wide. If you want to have more textbox padding or thicker right border, then the right padding of the table cell should be increased further.
Please refer to the existing Telerik skins, where this works like you request. The non-embedded versions of our skins are located in the \Skins\ subfolder of your RadControls for ASP.NET AJAX installation folder.
