Delete file with a button

Hello experts.
I have one update page where i'm uploading and deleting images.
For the delete function i use a checkbox.
Instead of that can i use a button?

<CFSET thispath = expandpath("./images")>
  <cfif structKeyExists(form,"foto1") and len(form.foto1)><!--- uploads a file to our website --->
  <CFFILE action="upload" filefield="foto1" destination="#thispath#" nameconflict="MAKEUNIQUE">
    <cfimage name="uploadedImage"
   source="#thispath#/#cffile.serverFile#" >
   ......
   .....
   <CFSET ServerFile1 = FILE.SERVERFILE></cfif>
 
   <cfif isdefined ("Deletimg_1")>
   <cffile action="delete" file="#thispath#/#artikel.Photo1#">
   <cfset ServerFile1 = images_1.jpg>
   </cfif>
   <CFFILE action="upload" filefield="foto2" destination="#thispath#" nameconflict="MAKEUNIQUE">
   <cfimage name="uploadedImage"
   source="#thispath#/#cffile.serverFile#" >
   ......
   ......
   <CFSET ServerFile2 = FILE.SERVERFILE>
  </cfif>
  
<cfquery name="artikel" datasource="#dsn#">
SELECT a.Art_ID, a.Photo1, a.Photo2
FROM dbo.artikel a 
WHERE Art_ID = <cfqueryparam value="#URL.Art_ID#" cfsqltype="cf_sql_numeric"> OR ( -1= <cfqueryparam value="#WADA_URL_Art_ID#" cfsqltype="cf_sql_numeric"> AND Art_ID=<cfqueryparam value="#SESSION.WADA_Insert_dboartikel#" cfsqltype="cf_sql_numeric">) 
</cfquery> 
 
<cfparam name="SERVERFILE1" default="">
<cfparam name="SERVERFILE2" default="">
 
<cfif CGI.REQUEST_METHOD IS "POST">
<cfinclude template="Includes/uploadhelper.cfm">
<cfquery name="imageupload" datasource="#dsn#">

SET photo1 =<Cfif len(ServerFile1)>'#ServerFile1#'<cfelse>photo1</cfif>,
    photo2 =<Cfif len(ServerFile2)>'#ServerFile2#'<cfelse>photo2</cfif>
