I think you're confused. Try the following little demo worksheet, and
all will be clear:
{{{id=15|
def myshow(G, *args, **kwds):
filename = 'sage-%s.png'%randint(0,1000000)
G.save(filename, *args, **kwds)
html("<img src='cell://%s'>"%filename)
///
}}}
{{{id=14|
print "First plot sin:"
myshow(plot(sin,0,2),figsize=[2,1])
print "And now for cos"
myshow(plot(cos,0,2),figsize=[2,1])
print "Cool, eh?"
///
First plot sin:
<html><font color='black'><img src='cell://sage-213578.png'></font></html>
And now for cos
<html><font color='black'><img src='cell://sage-462904.png'></font></html>
Cool, eh?
}}}
