Alpha version 3.23.09.12 is available at

https://sourceforge.net/projects/fldigi/files/alpha_tests/

Many of you may have used the MFSK image mode that is routinely 
transmitted by the VOA broadcasts.  Heretofore fldigi only provided a 
macro or a somewhat inconvenient dialog to select and transmit an image 
in MFSK mode.  This version has a 3rd method

   Image DnD
     * Add Dnd Image to TX panel
       - allows operator to insert image processing into TX text stream
       - drag image from system file viewer and drop on to TX text panel
       - functional for MFSK in 16, 32, 64 and 128 tone modes.

Open a file folder to the location of your image files that are suitable 
for MFSK transmission.  These images should be constrained to be 240 x 
200 or less for reasonable transmit times.  Optionally prepare fldigi 
for the MFSK image transmission by entering some suitable text to 
precede the transmission.  You may be sending the image, blossoms.jpg, 
for example.  One might enter:

Here is an image of my apple trees in full bloom.

Then drag and drop the the image file from the files folder to the 
transmit text panel in fldigi.

The TX panel text will then change to

Here is an image of my apple trees in full bloom.
Image: blossoms ^!

The ^! is the character sequence used by the fldigi TX parser to 
indicate that there is a pending execution command.  In this case it is 
to transmit the blossoms.jpg file.

Add a ^r to the next line and then press the T/R button (if not already 
transmitting).

This then appears in the Rx panel (on a Linux machine)

Here is an image of my apple trees in full bloom.
Image: blossoms <IMAGE:/home/dave/.fldigi/images/MFSKpics/blossoms.jpg>

Sending Pic:240x160C;

and the MFSKpic image transmission begins.  At the end of the image the 
TX parser will find the ^r and return the program to the receive mode.  
You could of course have added some ending text before the ^r, such as 
"I can't wait for the apples!"

I expect to see a lot more MFSK activity on 20 meters now.  Try sending 
an MFSK-16 CQ with the TX RSID enabled.  Try hanging out around 14073.0 
to 14074.0 KHz.
