upload to ftp folder with indesign script

Question

I am using indesign CC 2014 I have embedded "FTPConnection.jsx" that "Peter Torpey" wrote. then I wrote these codes to upload files to my server. Everything works fine, however files do not open correctly. I tried to open them with Notepad++ and I saw that while uploading files, the jsx changes them.

var ftp=new FTPConnection(false);
var acik=ftp.open("192.168.0.1","21","username","password");
if(acik==true){ftp.put(File(myFilePath),"images/1.png");}
ftp.close();

this is sample of original image:

‰PNG IHDR q Ò üÇF pHYs =5 =5ùäğ] IDATxÚìİ1¶«<£&è3OÁ#¨µ< <ç7òH+tÚ!Sğ*prà´C¦@ÒA‡»Ïù›ó—?~ÀHHì§ÖzÖ­{¿³÷! éEˆ_???¿ Ø6…

Answer 1

The first thing I'd recommend trying is to call

ftp.setEncodingBinary();

before the call to put().

FTP supports two modes of transfer: ASCII and binary. In ASCII mode, the default, only seven bits per character are transmitted. This is sufficient for standard ASCII-encoded text files. For files with multi-byte encodings and for binary files, the binary FTP mode is required.
