Hey Joe,
I'm just a dabbler with Python (at present), so I can't answer that.

Python and Ruby have many tools for doing web-related tasks, so there may be
ways to fine-tune the output.
Keep it in mind when you're looking for solutions.
On the AppleScript front:
-------------------------------------------------------------------------------------------
set pathToRelativize to "/Users/jgill/Documents/Web/CHOG/CHOG1and1/Archive
Photos/Juvenile-Shag.jpg"
set referencePath to "/Users/jgill/Documents/Web/CHOG/CHOG1and1/Commoner
Species Photos/Shag.htm"
set relativePath to getRelativePath(referencePath, pathToRelativize)
--> "../Archive Photos/Juvenile-Shag.jpg"
-------------------------------------------------------------------------------------------
--» HANDLERS
-------------------------------------------------------------------------------------------
on getRelativePath(refPath, filePath)
set relativePath to {}
set {oldTIDS, AppleScript's text item delimiters} to {AppleScript's text
item delimiters, "/"}
set refPathList to text items of refPath
set filePathList to text items of filePath
repeat with theNodeNum from 1 to (length of refPathList)
if item theNodeNum of refPathList ≠ item theNodeNum of filePathList then
set relativePath to ".." & "/" & items theNodeNum thru -1 of
filePathList
exit repeat
end if
end repeat
set AppleScript's text item delimiters to oldTIDS
return relativePath
end getRelativePath
-------------------------------------------------------------------------------------------
This is not pretty, but it's uber-fast. (I've left error-checking to you.)
No doubt it's similar to what you've built for yourself.
You've got the choose-file part of the script under control?
My personal preference is to avoid choose-file/folder dialogs and use the
Finder to locate files – then script the Finder-selection. But of course that
doesn't always fit perfectly with every work-flow.
