great. However, I am have a view with all my users thumbnails
displayed and am trying to make it so when you click on a thumbnail of
their avatar, it shows that users profile. In order to accomplish

Attachment_fu - watermark tmp file before saved to S3
Hi there,
I''d like to use RMagick to watermark an image in the tmp directory
before Attachment_fu saves it to Amazon S3.

''before_thumbnail_saved'' but this is no good because it''s for
thumbnails.

Making attachment_fu polymorphic
I am working on a small model mixin called attachment_kung to make
attachment_fu polymorphic, so you no longer need a different table and
Model class for every associated attachment (Productimage, Ad_doc,
etc). All you really need is one model and table to handel all your
attachments - in some cases, anyway. I have the code working, but have
run into one small hitch that I can''t seem to

attachment_fu and S3 -- cannot download file correctly
I don''t know why this isn''t working. If I download a word doc that I
uploaded, all I get is the S3 file path in the document. If I access
the s3 file path directly in my browser, it downloads the file
correctly.
Here is my controller method:

can't crop images using ImageMagick
I''m using Attachment_Fu to save several thumbnails of a photo
(resizing with ImageMagick)
But when I try to crop them, nothing seems to happen to the file I
want to drop and no error messages. I check the file timestamp of the
thumbnail I want to crop and it looks updated. What''s strange is that
ALL the other thumbnails and the original image''s file timestamps are

MiniMagick, and processing thumbnails...
I have a requirement that can''t be that outrageous....
I want to be able to upload an image, and have multiple thumbnails be
created for each. Then, I want to post process each image (the main
image plus the thumbnails) to add borders. The trick is that the
borders need to be different for each image. I thought I could use
the after_resize handler, but when I try to add a border to

How to spec an attachment_fu model
First off, I''m not trying to spec attachment_fu, I know it''s been tested.
But, I added some code to that model that I do need to test. Basically,
I need to somehow fulfill the "uploaded_data" property so I can actually
run my tests(otherwise they fail because of validations). The
"uploaded_data" field is what would grab the multipart data from form.

I''ve tried migrating acts_as_attachment to attachment_fu (just to see
if I could replace RMagick with ImageScience+FreeImage), but the
quality of the thumbnails is just horrendous, blurred beyond
recognition (downscaling a 1280x1024 to a few considerably smaller
thumbnails).

crispy sharp again.

attachment_fu replace thumbnail
hi.
I use attachement_fu and create this two thubnails of an image.
:thumbnails => {
:medium => ''380x>'',
:thumb => ''x100>''
}
Is it possible to replace the existing :thumb image with another image?
The main Image and the :medium should remain unchanged.
thanks
