idk here my way of doing the resize.
You can change the percent to change how large or how small you want the original image to be. My is on 40%...
Tag: timg
Replacement:
HTML Code:
<img src="{param}" border="1" width="40%"><br>
<a href="{param}" target="_blank"><smallfont>Click Here for Original</smallfont></a>
