Try these changes:

# before the csv reader, declare a single list
params = []

# in the csv reader, append each pair of params to the list as
# a tuple

for row in rdr:
    params.append( ( int(row[0]), int(row[1]) ) )


# use the lists of tuples to generate one image per tuple

for item in params:
    makeimg(item[0], item[1])

You could also skip the list generation entirely.

After the main function definition:

f = open(filename, 'r')
rdr = csv.reader(f)
for row in rdr:
    makeimg(int(row[0]), int(row[1]))
