As far as I know, there is no save function native to the Fabrica de Herois flash program. However, you can save the image you make, by using the print screen function. My "Prt Scr" button on my keyboard is just to the right of my F12 and just above the Insert key. Yours should be somewhere around there as well.
Just press the print screen key. That'll save a copy of your current screen display to the clipboard.
Now, open up Paint or GIMP or what ever image editing software you'd like and paste the screen capture into a new image. Use the square select tool to isolate the portion of the image you want to keep.
Now you can save the cropped image, upload it to an images haring website and then publish it here with the [img] tags.
Edit: and here's a little Cosmo the Moon Monkey, because I couldn't resist getting in on all this monkey business... or making that pun, apparently.
