Another option, which Rails has a lot of good documentation on, is to
create a row in your database which represents the image file, and
contains all the related meta data as well as a unique id number, and
then just keep the actual images in the filesystem named #.jpeg or
some such thing,

hm, seems strange eh, you'd think this is something that is just
possible.
many thanks for the link, i'll work it tonight.
alternatively i'll have to copy the image to the file system after all
and serve it from the webserver.
cheers

Roland just showed you how to inline it.
Here's a little article on the technique he's using:
http://jimbojw.com/wiki/index.php?title=Data_URIs_and_Inline_Images
However, as Jenna said, this technique doesn't work in IE. Her first
suggestion is probably the path of least resistance.

Hi Jenna, Roland
Thanks for your responses.
How can I get the image inline in the html, rather than downloading it
to the user?
I'm not at all sure how to use markaby to stream the image data into
something the img tag will understand.
Many Thanks for helping

Mmm, indeededly, though data: uri's don't work at all in internet
explorer, quite the bummer if you care :)

Well, you could sorta do img(:src => file_data), using the data: URI scheme.
def data_uri(file_data, mime_type="image/png")
"data:#{mime_type};base64,#{[file_data].pack('m*')}".strip
end
Then you could just do img(:src => data_uri(file_data)), and it should work.

Make a controller with a get method to retrieve the image, then, have
some code like this in it, supposing image_data is a string or
something:
headers['Content-Type'] = 'image/png'
headers['Content-Length'] = image_data.length.to_s
return image_data

hi all
just working on my first camping hack and new to ruby as well.
i've figured some things out and uploading images into the database,
but i'm not sure how to get the data displayed in the browser.
i'd like to stream it straight from the db, not copy it to the fs first.
obviously img(:src
