Attachment_fu won't upload images to S3 on Windows XP?

I've been slugging through Google posts on why attachment_fu doesn't want to upload the entire image file to S3 on a Windows XP machine and fine no conclusions as to what I should do? Here is a link with many suggestions. I've tried all of them and none work for me. Attachment_fu on Windows? - Rails - Ruby-Forum I try .png, .jpeg and .gif and they all simply put a ghost file up on S3 without any content. Does anyone out there have Rmagick, attachment_fu running on a Windows XP machine and using Amazon's S3? Would you mind sharing what changes you made to attachment_fu to make the photos upload correctly? S3 gets a VERY few bytes such as 25 bytes for a 370k graphic file. When I show the graphic all I see is a 'placeholder' where the :thumb or public_filename should go. Any help is greatly appreciated. Kathy
