I created something most similar to this one, except for a few things:

• I only specified the width, because that way the width/height ratio will remain the same.
  
• I didn't use the optionfield, thumbnails might just aswell always show a border, or if you would rather have them never show a border, you might set it to

   border="0"

  now all thumbnails are uniform
  besides that, users can't specify huge borders anymore
  
• and after

  target="_blank"

  i added

   alt="thumbnail picture, click to see fullsize"

  this way, on mouseover, the users will see a tooltip telling them it's a thumbnail.

resum?; this is what it my code is:

<a href="{param}" target="_blank"><img src="{param}" width=100 alt="thumbnail picture, click for full size"></a>
