FTP command - damaged file (german MacOS 9.2)

[Ralf K=?ISO-8859-1?B?9g==?=nner]

Dear list,

the following line does almost all the job: opening a connection, logging
onto a server and sending a binary file:

put URL "file:/HD/desktop folder/test.jpg" into URL
"ftp://UserID:password@www.myServer.de/test.jpg"

The only thing that fails is that the uploaded file can not be displayed in
the browser. When trying to open the file, after downloading it back again
from the server to my local HD via Fetch, PictureViewer and PhotoShop show
up with a "Could not open - file is damaged" dialog.

Any help is really welcome, thank you and best wishes,

Ralf
