For the ipload destintaion you do not add the imagename. Destination is a folder not a file.
The resulting file name can be retrieved from cffile variable.
Like this:

<cfif IsDefined("FORM.file") AND FORM.file IS NOT '' >              
<cffile 
action="UPLOAD" 
filefield="form.file" 
destination="c:\websites\171210jc2\admin\events\#session.folderpath#\" 
nameconflict="makeunique">  
 
<cfset imageName = "#cffile.serverFile#.#cffile.serverFileExt#" >
 
<cfimage action="info" structname="imagetemp" source="c:\websites\171210jc2\admin\events\#session.folderpath#\#imageName#">
<cfset x=min(200/imagetemp.width, 100/imagetemp.height)>
<cfset newwidth = x*imagetemp.width>
<cfset newheight = x*imagetemp.height>
<cfimage action="resize" 
source="c:\websites\171210jc2\admin\events\judsonmusic\#imageName#" 
width="#newwidth#" 
height="#newheight#" 
destination="c:\websites\171210jc2\admin\events\judsonmusic\Thumb_#imageName#">
 
</cfif>

ACTUALLY I CHANGES MY CODE TO THIS:

<cfif #IsDefined("FORM.file")# AND #FORM.file# IS NOT ''>              
    <cffile
    action="UPLOAD"
    filefield="form.file"
    destination="c:\websites\171210jc2\admin\events\#session.folderpath#\#imagename#"
    nameconflict="makeunique">  
   
    <cfoutput>
    <cfimage source="c:\websites\171210jc2\admin\events\#session.folderpath#\#imagename#"
    action="resize"
    width="150"
    height="200"
    destination="c:\websites\171210jc2\admin\events\#session.folderpath#\thumb_#imagename#"
    overwrite = "true">
    </cfoutput>
   
</cfif>


IT WORKS ON A WINDOWS MACHINE BUT NOT ON A MAC! WHY???:::::::::::::::::::::::::::::::::::::

When i run it on a mac I get the following error:

 An exception occured while trying to write the image.
Ensure that the destination directory exists and that Coldfusion has permission to write to the given path or file. cause : java.lang.NullPointerException
 
The error occurred in C:\Websites\171210jc2\admin\myEvents.cfm: line 25

23 :     width="100"
24 :     height="100"
25 :     destination="c:\websites\171210jc2\admin\events\#session.folderpath#\#imagename#"
26 :     overwrite = "true">
27 :     </cfoutput>

I have narrowed it down to safari.

Safari doesnt like this:

<cfset imagename = listlast(form.filename,"\")>

it outputs the full path for some reason but in FF and IE is just shows the file name.

WHY?????

We will see. I assume I will be able to help :-)

But please take a look one moment at the actual question. You replied that it "seams" to work. That is not acceptable. The purpose of my support is to get you learning from your question not to do your job and get your code working.
So my question to you is: do you see what mistakes you made in your code and did you learn what is the correct way of uploading files and generating server side uploaded file names?
