Based on my experience and simple web protocols, you can't do what you
want. You could however combine all the images into one file (a zip file)
and download that zip file. In your controller you could do something like
this:
import os
import StringIO
import zipfile
tempfile = StringIO.StringIO()
ziph = zipfile.ZipFile(tempfile, 'w', zipfile.ZIP_DEFLATED)
# psuedo code here
loop through all the picture files you want to download:
ziph.write(file) # add the file to the zip file - 'file' needs to be
full path of the file
ziph.close()
response.headers['Content-Disposition'] = 'attachment;filename=images.zip'
response.headers['Content-Type'] = 'application/zip'
rtn = tempfile.getvalue()
tempfile.close()
return rtn
Hope this helps.
If you truly want to download multiple files at once I think you're going
to have to go with some javascript magic. Since it is a bit of
non-standard way of doing things I've never attempted...
