I am obviously doing something stupid or not understanding the
difference between HTML file references and python script file
references.
I am trying to create a thumbnail of an existing .jpg file. It is in
the directory 'temp', which is below my script
I can display the file with <img>, but Image.open does not see it.
I think it is probably a path problem, but I have tried '/temp/
fred.jpg' and './temp/fred.jpg'
Can anyone help, please
PS I am using mod_python on a Linux Apache 2 and python 2.5
