Resolution of jpegs is low on some web sites. Can I correct this?

[Guest]

Two computers side by side, both running Win XP, both using the same router
connected to the same cable modem, both displaying the same web sites on IE
6.0, SP2.

One computer (desktop) displays all images clearly (high resolution). The
other (laptop) displays some jpegs clearly, and some are fuzzy. When you
view properties of the images, some show the same byte count on both machines
and are clear, while others show less than ONE-HALF the number of bytes on
the laptop (and are fuzzy) as the number of bytres on the desktop. The
problem is only with certain jpeg images on certain websites.

Is there some IE setting that I can change to prevent this display of lower
resolution images? I've checked the source coding of the website between the
two computers, and there's no difference. Why does the laptop change the
byte count of certain images and display them in a pixellated fashion?

Did you try changing your screen resolution? Right click on the desktop,
Properties | Settings.

Margaret,

Yes, and I should have mentioned in my question that screen resolution
settings have no effect on the byte count of the jpeg images. It HAS to be
something in IE, as Netscape doesn't have the problem.

Thanks for trying. Any other ideas?

Hi,
Some possibilities:
1. Internet Options> Advanced, uncheck "Enable Automatic Image Resizing."
2. Try a DPI setting of 96 (Control Panel> Display> Settings> Advanced> Font
Size.)
3. See this discussion:

Even if the laptop computer isn't a Dell. It's worth looking at that
registry key.

4. Unlikely with a broadband connection, but is a program running that would
be compressing images to provide faster display of pages?

Hope this helps,

Don,

All good points, but none help. The first thing I tried was to uncheck
"Enable Automatic Image Resizing" and reset the DPI to 96 for font size.
Dell had me change the registry key on two locations (the laptop IS a Dell,
by the way) with no effect.

I think your 4th point is exactly the CAUSE of the problem, but I can't
figure out a FIX. We did set up a dial-up ISP to use on a recent road trip
when we thought wifi might not be available. One of their options was a
"hi-speed" dial-up connection, which their tech support people told me did
exactly what you suggest. That is, it caused the browser to reduce the
resolution of graphics for faster loading.

Trouble is, I have uninstalled that software. Completely. Also, a
different (Netscape 8.0) browser on the same laptop displays the jpegs at
full byte count, while IE displays some at full byte count, and some at
between 1/2 and 1/3 the number of bytes as Netscape. AND, it doesn't do it
to ALL jpegs, just some of them, but always the same ones on a given web
site. It's as if there is some coding in the HTML that tells IE which files
to display at full resolution, and which to display at partial. I've used
"view source" to examine the HTML and can't find anything there.

Any other thoughts? The "hi-speed dial-up" ISP tech support folks tell me
that once I uninstalled their software it should have no lingering effects on
IE. I'm doubtful about that, but what can I do?

Have you cleared the IE cache? From IE> Tools> Internet Options> General>
Delete files (and delete offline content when that dialog pops up) It's
often recommended that the TIF folder be kept at about 50 MB (Settings.)

Or, do a careful search of add/remove programs to see if any type of
accelerator program is still listed.

Or, check IE> Tools> Manage add-ons. Anything unknown or suspicious?

With no programs running except IE, bring up task Manager via Ctrl-Alt-Del.
Look at Processes and search google for any that you can't identify.

Don,

YOU DID IT!

I had looked at the "Add-ons" list but didn't know what many of them were so
left them alone. But I never thought to do what now seems obvious (since you
mentioned it) and delete all the temp files.

DUH!

That solved the problem. I'd still be curious about the algorithm (or
whatever) that caused IE to select only certain JPEGs to display at lower
resolution, and how to turn it off or on, or how to adjust it, but my problem
is fixed and I thank you again!!

End of discussion for me.
