Reportlab Image object opens filehandles

[Michael Schmitt]

Hello.

I am trying to build a pdf document using:
---
from reportlab.platypus.flowables import Image
lst = []
for filename in imageFiles:
    I= Image(filename, width= 300, height= 300)
    lst.append(I)
---
Creating an Image object seems to open a filehandle, so if the size of 
imageFiles increases, I get "IOError: [Errno 24] Too many open files" on a 
Solaris machine, where the number of simultaneously opened filehandles 
seems to be limited to roughly 255.

Is there a way to produce a pdf document with a large number of images 
without running into the problem of too many open filehandles?

Thanks for any hints.
Michael
