Files that affect images

In this forum there are some experts/MVPs. I hope they are expert enough to
answer me.

I NEED to know what files of XP affect the visualization of images and if
those files have been changed in the updates of XP since May/June 2012
about.

"Visualization of images" suggests the OP wants to know more
about graphic display or graphic editing applications (e.g. IrfanView,
MSPaint, Photoshop etc.) None is part of the XP Operating System,
although standard installations of XP make MSPaint the default
graphic app.: but users can use / File / Association to select another
as default.

Isn't there also "Microsoft Imaging" or some such name - I think it has
a pastel landscape as its icon? That's certainly the default on the
machines where I work, which have XP. Though they also have Office, and
I don't know if it came with that; I just checked here and it isn't
under my Office 2003, but I may have chosen not to install it (IrfanView
being so much better), I can't remember.

But if GF can explain what problem he's having, we can probably help
more easily.

Since May/June 2012 about I am suffering the plague I told in my previous
message "Images unexplainably changing". Shortly, some images unexplainably
become reddish in certain circumstances and then they return to normality.
Today I have also found out that some other images are permanently and
unexplainably darker than they were before May/June 2012.
This happens with the viewer of XP, with JpegView, with Picasa, therefore
there is a common point for all the viewers. I think the culprit might be a
file/program of Windows that all the viewers use to show images.

Or, could it be an intermittent fault on your Graphics card, or your Monitor
?
More investigation is required.

Odds are very remote that its a XP problem.
Odds are you are on the wrong track.
As others have said, its more likely vid card, vid card drivers,
or monitor. XP really does not do graphics, per se.
XP has built in drivers for VGA mode and thats about it.
Everything else is via vid card and vid card drivers.
When was the last time the dust was cleaned out of the vid card
gpu and computer cpu?
Try temp swapping monitor and vid card.
There is a known problem with ATI cards, the latest drivers,
and some games. The games appear red or pink.
The solution is to roll back to old drivers.

To meerkat and Paul:

The issue appears when I use a viewer to see images only. Image files seem
bewitched.
Everything else I see is perfect and it's always perfect.
That's why I can't believe the culprits are monitor or video card or drivers
of the video card.

Are the modification dates of the viewed files changed ?

It's possible to get around modification dates, with a root kit.
So there are forms of malware, that can "leave no traces" of what
they've been doing. An ordinary program making changes, should
alter the file dates (since the modifications would be made by
calling the file system).

While a program like ProcMon from sysinternals.com , can be
used to trace certain operations on the computer, I can't guarantee
to you that what is happening to your files, could be discovered
by such a program.

Windows does have CODECS for images. That doesn't mean that
calling a decoder, is necessarily going to cause an encoder to run,
and write to the file.

If a person had installed a software that "automatically color
corrects photos", then something like this might happen. You have
to think carefully, about all the shareware or scareware you've installed
recently. Like those clever scarewares that hide all your files, and
need "unhide.exe" to get the files to become visible again. Anything
is possible, if you download a lot of freebies of unknown origin.

So, just to be clear: the image files themselves are not being changed,
only their appearance when viewed on that particular computer (in other
words, if you copy them to a different device - even your TV if it has
card or USB ability, or another computer, or even your camera - they're
OK)?

Try IrfanView, though if it is a common piece of code that may suffer
too (though I know it doesn't use the common JPEG viewing code since it
[IrfanView] is not susceptible to the malware code exploit that was
around a few years ago).

Always possible (or the drivers therefor), but he says it's only when
viewing images, so unlikely.

If you view one of these images _not_ full screen, is the rest of the
screen OK (especially if it contains images, such as a web page)?

(Another "viewer" you could try is your web browser. That may or may not
use the common code libraries.)

Have you tried taking a screenshot then open it from a different PC?
If it looks corrupted when viewed on other PC, then it's definitely a
software problem, not hardware. If so, post it on imgur then post the link
here for everyone to see.
