Hi Mike,
Thanks for that! I was doing the same thing at the same time:)
My code for setting up the server:
local sTempMedia
command setTempMedia
### Set the location of the tempMedia folder
# set the defaultFolder to the folder containing the stackfile
set the itemDelimiter to slash
get the effective filename of this stack
#set tempMedia folder location
put item 1 to - 2 of it & "/tempMedia" into sTempMedia
end setTempMedia
on startHTTPServer
# Launch httpd server to serve local images
setTempMedia
httpdStart "NewRequest", 8090, "imgEngine Server"
end startHTTPServer
on stopHTTPServer
httpdStop 8090
end stopHTTPServer
on NewRequest pSocketID, pRequest
local tPath
put sTempMedia & pRequest["resource"] into of tPath
if there is a file tPath then
local tData
put url ("binfile:" & tPath) into tData
httpdResponse pSocketID, 200, tData
else
-- not found
httpdResponse pSocketID, 404
end if
end NewRequest
My code for embedding it:
# tFileName is just the name of the file. i.e. MyFile.jpg
put "http://localhost:8090/"; & (tFileName) into tHero
# other code would follow to meld tHero into my html
and works just amazingly well!!
Thanks again for all your help!
I sure hope this helps someone else as well!
Best,
Steve
