There are a few different was to do this but probably the easiest is to
save the image to disk. Something like:
[% FILTER null;
USE im = GD.Image(50,50);
# allocate some colors
black = im.colorAllocate(0, 0, 0);
red = im.colorAllocate(255,0, 0);
blue = im.colorAllocate(0, 0, 255);
# Draw a blue oval
im.arc(50,50,95,75,0,360,blue);
# And fill it with red
im.fill(50,50,red);
# Output binary image in PNG format
im.png | redirect('/path/to/image.png');
END;
-%]
<img src="/url/to/image.png">
If the images are reusable, you could put in some logic to check if the
file exists already before regenerating.
