You want resize the picture itself or do you want diplay the picture only 50%?

It's better to resize the image before the upload. 

**1. Media parameters**

Since **!!(green)R5.5.8!!** you can resize an image by appending the following media parameters:
e.g. ##~file:/image.png?200x400##

  * resizing
    * ##400x300## - width x height (pixel)
    * ##0x700## – height (pixel) 
    * ##600## - width (pixel)

**2. Wrapper and autoresize**
##""%%(wacko wrapper=page wrapper_width=500)file:/image.png%%""##
##""%%(wacko wrapper=box wrapper_width=600)file:/image.png%%""##

A wrapper might also be useful if you use it with an unknown image size, e.g.
##""{{randomimage global=1}}""##

**3. HTML & CSS**
Using percentage is not supported, but if you have HTML enabled, you can use CSS style to do that e.g.
##""<# <img style="width: 50%; height : auto;" align="left" alt="WackoWiki" src="file/global/wacko_logo.png"> #>""##
