wxPython: images from URLs

[Anand Pillai]

This is the straight forward way to do this in wxPython
but somehow it always pops up that ugly error window.
I remember trying many options to do this purely using
wxPython (wxWindows), but I failed. 

If you use PIL in your program you can conver the
wx Image instance to a PIL image of type BMP and then
display it by reconverting it back to the wxImage
instance. PyWiew has methods to do this. The source code
is available somewhere in my Python page at
http://members.lycos.co.uk/anandpillai . I no longer
maintain that program, but the latest source code should
be available there.
