how about upload an image?

[James]

if any one knows how to upload an image to a server and save that image
as is and also save a smaller thumbnail of that image to the same
directory, please let me know the code.
think u!

Ooh! Thanks for the link.

Something else you might want to check out, James, is RMagick
(http://rmagick.rubyforge.org/). This is a Ruby interface (not in the
Java sense) to allow image manipulation via ImageMagick, or
GraphicsMagick. It's a bit tedious to install, but it appears to be
quite powerful.

Best of luck,

James H.

I'd like to say, I installed RMagick, and expected to have to do a bunch
of work to get the image info and some relatively involved manipulations
I wanted, but it was dead simple. RMagick kicks butt.

Here's a snippet from a Rails app of mine. (This is simple
thumbnail-making, not the stuff I was talking about above.) image_data
is the contents of an uploaded image, as a string. THUMB_GEOMETRY is
"120x120>", meaning shrink to fit inside a 120x120 box unless it already
does.

image = Magick::Image.from_blob(image_data).first
image.change_geometry(THUMB_GEOMETRY) do |cols, rows, image|
image.resize! cols, rows
end
image.write File.join(RAILS_ROOT, 'public', thumbnail)

Cheers,
