Assuming what you need is a new file with img1 changed to img1 , img2 , img3 .. so on . The following code should work . You will have to go one line at a time .

i=2
with open("test.html")as f ,open("test2.html",'w') as f1:
  for elem in f.readlines():
    if 'http:localhost/img' in elem:
      f1.write(elem.replace('http:localhost/img1','http:localhost/img%s'%i))
      i+=1
    else:
      f1.write(elem)

You can do:

s = s.replace('http:localhost/img1.jpg','http:localhost/img2.jpg',1)

The third param is the max ocurrences to replace.

You can see it in python documentation
