Rails - May 2009 - any way to submit an image as part of a form (Javascript?)

I would like to submit the data of a rendered image from the users
browser in a form. Is this possible? (My reasons are not illegal, by
the way). I''m going to be storing it in a database for viewing at
another time.

I know this question begs the question why not do it some other way
etc etc, and may get me some "What are you trying to achieve?", but I
would appreciate a straight answer.

Ahh, I see.  "Judge, I did not violate that person''s
copyright--all I
did was copy it for viewing at a later date."   lol.

The site from which this will happen has explicit permission for
copying of images.

If you had taken my word for it instead of presuming I would not be
posting this message.

Presumption is the sign of a person who has not reached maturity but
presumption in the face of a person''s word is absurd.

lol.

A web page is not allowed to sniff around on a user''s computer and look
for material to blackmail them with, e.g. a priest with 100,000 images
of naked children in his browser''s cache.

do you mean you''d like to allow users to upload images?

"I would like to submit the data of a rendered image"

What do you mean by "rendered"? Was the image generated via Flash or
something similar? If so, then the flash applet can just submit a POST
request (multipart/form-data) with the image as a string. Otherwise,
you''ll need to clarify exactly what you''re trying to do, as it
sounds
like you''re just trying to upload an image (which due to browser
security, *cannot* be done with javascript).

Hi Eric and pharington,

I''m not certain what you mean by "upload an image" and I
don''t mean an
upload from the user''s own harddisk as with an edit box for the path
etc.

So to clarify: rather I supply the user with a form that has an
''img''
tag to an image on another site and which the user can see (rendered).
If the user submits the form I get the server to itself fetch the
image from the other server but I am exploring the possibility of
directly uploading what is in the client''s browser to my rails server
avoiding that second fetch from the other server. It won''t save my
rails server bandwidth but it will save the other server.

I suspect you''ve already answered my question with the
''javascript
security'' mention, but I''m not sure.

Am I''m stumbling over the cross-site restrictions, irrespective of
javascript, and that there is no way of doing this?

I''ve been thinking about my previous post and have concluded I owe you
an apology for exactly the crime I accused you of: presumption. You''ll
see I presumed upon your motive for posting, which may have just been
humour rather than a snide remark. Looks like I;m the immature juve
after all.

So sorry for that.
