sitemaps should be dynamically updated or they go stale quickly.
But back to rel - I know it is currently used for relationship with
external document, but reality is, it's instructions to indexers.
things like rel="nofollow" are so specific to search engines they cause
confusion to some users who don't want to use the attribute because they
psychologically want their users to follow it (e.g. affiliate marketing)
and the phrase "nofollow" is counter to that.
I don't think a second attribute to instruct search engines is needed,
just expand the definition of rel to also encompass the relationship of
the node to the document when it isn't a node that generally links to an
external source (such as a[nchor] and link)
With the source element, the meaning of the attribute (and what
attributes are legal) changes depending upon the parent node, so there
is precedence for context influence attribute meaning already.

@Andrea :
Could you give me an exemple of code ? but this way need to specify
height and width ? The advantage of image tag is the autodetection of
these properties.
e.g. I have a character in my html page animated with jquery and i want
that the page to be responsive and i can't use breakpoint.
I have just to specified percentage width and let the height adjust itself.
When I resize the window, the character resizes itself, and jquery
calculates news coordinate for the animation.
Anyway, aside from my example that was just here to bring my thoughts, I
supposed that others persons had maybe encountered this problems of some
unwanted indexed images.
By the way, concerning the intellectual property, I agree with Michael.
You can reproduce an illegal situation of a copying a book on a html
page, use the noindex meta tag and diffuses it even if you are not the
author, it is probably illegal, but you can do it.
@Michael
Rel attribute is used for a relationship with another external document
from a source to a target, but considering that an image is already
included in the content, this would make it to do a relationship from
the source to the source, do not you think ?
A sitemap image node could be indeed another approach.
The subtilitie is that with an attribute you can change the src of image
without impact the fact that you don't want that this image particulary
is indexed. Moreover with a dynamic content displayed with a loop, you
can specify this attribute without take into account the image source.
Finally you can apply the non indexation on a fully range.
Whereas the sitemap need to be continually updated with the sources
unwanted.

That's what we do when we don't a link to be construed as related to
our page content itself (e.g. an advertisement)
But perhaps the right place for this isn't in the html itself but in
the sitemap file - maybe an image:priority child of the image:image node.
As far as intellectual property implications :
A) It is not the job of HTML itself to protect intellectual property
B) If it isn't being indexed in the image search, then it may still be
an intellectual property violation, but at least isn't one that is
bringing new business to the site away from the real intellectual
property owner.

Hi Aurélien
I haven't tested any case yet, but I usually prefer to maintain graphic
elements and page content separated in my pages too.
Now, it depends on what you mean by "no choice but to use an image
instead of ...css".
I incorporate graphical elements in form of transparent 1px gif images
and use the "real" graphic as a CSS background element.
Then I wrap all the content which is to be replaced by the image in an
element with display:none, so that only the graphic appears.
Would this solution help you?
BTW, I don't think that such an attribute could be implemented.
As a very basic caveat, consider the malicious use that could be done of
such an attribute, hiding potentially illegal content present in the
page.
