===Why a modification to the image action?===
The aim of this enhancement to the official image action is to:
- support HEIGTH and WIDTH parameters
- allow to create a link opening a new html page to display a full size image
===Usage===
Just use the action as usual (AddingImages) and add the optional parameters:
- WIDTH to define the width of the image to be displayed
- HEIGTH to define the heigth of the image to be displayed
- OPENFULL will create an anchor link to the image URL that will open a new html page to display the full size image when clicking on the picture
All 3 new parameters are optionals - OPENFULL is considered as TRUE when different from nothing.
""{{image class="center" alt="blabla" title="blabla" width="25" heigth="12" openfull="whatever"}}
