Hi,
A while ago I made a bookmarklet that blurs images in articles on
the english Wikipedia and reveals them when the user hovers over the
image. I now had a chance to test this as a skin.js extension.
For a start, users would have to opt in to this, which may not be
appropriate for casual readers brought to us from Google and other external
links. I'm not sure it's a good idea to make it a default for unregistered
users, many, if not most, of whom, might not want to be presented with a
pre-filtered version of Wikipedia, and would be surprised to be so
presented. It also presents a "slippery slope" argument in that nobody is
realistically qualified, nor would want to be tasked with, drawing the line
as to what images should and should not be treated thus. A similar argument
applies to textual content of articles; however we try to achieve
neutrality, it seems that there will always be some POV-pushers who will
argue the toss ad infinitum, and we don't accommodate them. Neither should
we accommodate those who do not understand that a value-neutral, world
value, is not the same as their value. These people have their own texts,
and I think that our response should be that they are welcome to them.
Nobody is being forced to use Wikipedia, after all.

To try this out you would have to copy or import this code into your
own skin.js and skin.css files which are available e.g. under
http://en.wikipedia.org/wiki/Special:MyPage/vector.js

This only works in recent desktop versions of Opera and Firefox and
only on devices where you can easily hover. It may show some images
that it ought to blur for boring reasons. Spoilers ahead if you want
to try it.
Browsing around with that is quite interesting. Some findings: it is a
bit annoying when UI elements (say clipart in maintenance templates)
are blurred. The same goes for small logo-like graphics, say actual
logos, flags, coat of arms, and actual text, like rotated table
headers. I did expect that blurred maps would be annoying, but I've
not found them to be. Take
http://en.wikipedia.org/wiki/Dagebüll as
example, the marker and text are overlayed so they are not blurred,
and I can recognize the shape of Germany fine.
I note that there is a perceptual problem if you click around to
explore how blurring affects the experience as that does not reflect
what a user would do. I noticed that my impression changed a lot when
switching from actually paying some attention to the articles to
randomly moving to the next article just looking at the images.
Pages, or parts of pages, that largely lack content (say all you get
on a screen is lone line of lead, table of contents, and image plus
map on the side, or a stub that has four sentences and an image).
There it's a bit odd, in stark contrast to an article like BDSM where
I felt blurring is very unobtrusive.
Another thing I've noticed is that I pay a whole lot more attention to
the images when I focus them, decide to hover over it, reveal it, and
then look at it, maybe read the caption and so on. I also noticed I do
not really bother to read the captions before I hover and rather
decide based on the blurred picture itself (I ignore most captions
usually, so this is unsurprising). There are also many surprises,
where images do not come out in the clear as you would have expected
from the blur.
My impression is that it actually makes it much easier to think about
if an image is well placed where it is. If there are several images,
you can focus more easily on just the one, and you remove to some
degree the "status quo" effect, where you may be biased to agree with
the placement because someone already placed it there.
Images where red tones are used a lot seem to be rather distracting
when they are blurred. Blue and green and yellow and black and white
and so on are no problem, and the red tones are no problem when the
image is crisp. Not sure what's up with that, I have not noticed this
before. It would of course be possible to manipulate the colours in
addition to the blurring.
Largely black and white bar charts and tree diagrams and illustrations
of data like them are also annoying when blurred, in part because
there is inconsistency as some of them are not blurred because they
are made not as image but using HTML constructs. They are perhaps too
much like text so unlike a photo with many different colors they are
harder to just ignore using one's banner blindness skills. There is
also a noise factor to this,
http://en.wikipedia.org/wiki/Electromagnetic_induction for instance
compared to
http://en.wikipedia.org/wiki/Morse_code -- in the former
the graphic in the infobox is fine blurred while the latter irks me
when blurred.
Generally though the added nuisance is hardly worth mentioning, it
works surprisingly well (well, this was the first thing I thought
about when I learned of the image filter, but it does work a bit
better than I had expected initially, and some issues would be easily
fixed, like blurring only images larger than 50x50 would take care of
most of the UI graphics for instance). So having conducted this
experiment, I think the need to have some images hidden while having
others in the clear, where the com- munity as a whole decided to show
rather than hide, as in omitting them for all users, is not a
legitimate need.
