Hi, I have been working a little on this problem. I noted that if a photo that  
had a file name with non-ascii characters (æåø),  I would get this error 
message "Error Occured: Invalid signature" We cannot proceed further. This I 
found with images taken with my Olympus mju 500.  I would suggest looking 
into how the filenames are passed to flickr, as it appears to me that flickr 
internally support æøå photo file names. I am not a good programmer myself, 
but this should be fixable, I think.

However, there appears to be other "triggers" for this error message as well. 
I have experienced with my Nikon D80 camera that pictures without any 
non-ascii characters fail to load up to flickr, with the dreaded "Error 
Occured:Invalid Signature" error message. Somewhere on a net forum, a list of 
causes for this problem was posted by another user, but right now, I can't 
remember where.

If someone with more development experience than me is interested in trying to 
improve the flickr uploader, I have some time to do the trial and error work.
