Hi Luis,

The presence and position of the 'waterfall colour to dB' legend is 
configured in SL's Screen Capture settings:

http://www.qsl.net/dl4yhf/speclab/perisced.htm#screen_capture

Set the checkbox 'color legend'. You can also select *where* (in which 
corner of the screenshot) that 'legend' shall appear.

Uploading captured images via FTP requires a command-line driven 
external FTP client.
There is one integrated in windows, but it's so terrible to use (and 
control) that I would try something different. You need to create an 
old-fashioned batch file to do this (if no modern FTP client is available):

http://www.qsl.net/dl4yhf/speclab/perisced.htm#ftp_upload_batch


The FTP upload command can be invoked from the 'screen capture extension 
macros'. These commands are invoked shortly *after* every timer-driven 
screen capture.

For more details, I suggest to ask the question in the Spectrum Lab 
Users group, there may be users more familiar with command-line driven 
FTP utilities under Windows 7 / 8 (which I hardly use myself).

Hope this helps,
   73,   Wolf  DL4YHF .
