Search & Replace - field parsing?

[SrNupsen]

Hello,

I guess this is actually meant for Parahead (hello if you read this!): I'm trying to make use of the Search and Replace addon to allow users to insert images in their posts like this:

[bilde1]

However, having the addon replace

[bilde(##)]

with

<img src="/bilder/<Field: CustomField_illustrasjon(#1#)>" />

is of no use, as the Field isn't parsed! Would this be difficult to achieve with this addon, or am I doing something wrong?
