I am not sure what you are trying to do ... but i'll give it a try ... & see if it helps you ...

your existing code is fine (i think)

<cfset numImages = 8>
<cfloop index="i" from="1" to="#numImages#">
<cfquery name="getDBimage#i#" datasource="#request.dsn#">
SELECT img_Text
FROM dbo.All_Images
WHERE img_ID = <cfqueryparam value="#i#" cfsqltype="cf_sql_numeric">
AND Artimages_ID = <cfqueryparam value="#URL.Art_ID#" cfsqltype="cf_sql_numeric">
</cfquery>
</cfloop>

>> But for the query outputs :

i think u need to loop all over again ...
<cfloop index="i" from="1" to="#numImages#">
     <cffile action="delete" file="#thispath#/#Evaluate('getDBimage#1#.img_Text')#"> <!--- should this be file upload instead of file delete ? --->
     <CFSET "ServerFile#i#" = CFFILE.SERVERFILE>
</cfloop>

similarly ... u'll need to use evaluate again in the subsequent code ....

>> The updatequery
             <cfquery datasource="#request.dsn#">
             Update dbo.All_images
             SET img_text = '#Evaluate("ServerFile#i#")#'
             WHERE Artimages_ID = <cfqueryparam value="350" cfsqltype="cf_sql_numeric">
             AND  img_ID = <cfqueryparam value="1" cfsqltype="cf_sql_numeric">
             </cfquery>


>> The insert query:
<cfquery name="imageupload" datasource="#request.dsn#">
            Insert into All_images (Artimages_ID,img_ID,img_text)
            values (#Url.art_id#, 1,'#Evaluate("ServerFile#i#")#')
</cfquery>

>> i need a help

does this help ?

PS: U could even close this Q's to get ur Q points back - which u can use for further Questions ...
