ASKED QUESTIONS
Q.
How do I turn off the AOL Compression feature?
A.
See our INSTRUCTIONS
section.
Q.
Why do my images look more blurry on AOL's Browser and why do some have
black bars on them!
A. America Online utilizes graphics compression software
that speeds up the delivery of web pages to it's members by compressing
images and various multimedia applications. Images that are BMP, GIF
or JPG are converted into the proprietary Johnson-Grace image format
.ART. All AOL members have the option of deselecting "Used Compressed
Graphics" in their Web Preferences.
Recent versions of some of the popular Image processing software such
as Photoshop 4 - 5 put additional information in the image headers.
The Johnson-Grace compression software interprets this addition information
and attempts to compress it, resulting in black areas on the image.
This can be rectified by using Photoshop 3.0 to save JPG's.
Also, saving JPG's and GIF's without "Thumbnails" in the newer
versions of Photoshop will optimize your images for AOL's browser as
explained in detail in the Graphics Compression area of Webmaster Info.
Q. OK, I have
deselected "Use Compressed Graphics" in my WWW preferences
and the images still look the same! What am I doing wrong?
A. This is a Caching issue. In your WWW preferences
you can set your history to "0" pages and clear the History.
You must also delete the files in your Temporary Internet Files folder.
Holding down the "Control" key on your keyboard and simultaneously
mouse-clicking on the Browser Reload icon while the browser window is
active will also clear your proxy cache and display the latest data
from the website.
Q. When I
create a large JPG as a background, it displays as tiled in the AOL
browser, why is that? What can I do to display a large graphic background?
A. JPG's that are wider than 640 pixels are scaled down
as part of the compression algorithm set up by the Johnson-Grace compression
software. A GIF, even though it's larger in size it can by used as a
replacement for large background JPG's . Another resolution is saving
the JPG as "Progressive 3-pass" which the current version
of the Johnson-Grace software does not recognize.
Q.
I am still getting old pages and I am certain that the site has been
updated, how do I clear my BROWSER CACHE?
A. Even though AOL's Proxy cache is updated every 24 hours, a
member can clear their Browser Cache and force the reload of a page.
This is done by either reducing thier History to "0" and manually
clearing all pages in history or by holding down the SHIFT
key on their keyboard and mouse clicking on the AOL browser reload icon.
The latter will completely clear all items in history.
INSTRUCTIONS
Option #1
(Turn off AOL's graphic compression)
1. Open America On-Line,
and make sure that you are connected to the internet so you can test
your settings later.
2. Open the AOL web-browser as if you were going to a website as usual.
3. Look at the top of your AOL browser window. You will find a set of
option buttons. Among them are Back, Reload, Forward, etc. Click the
"Prefs" (preferences) button.
4. A new window should open with different tab options. The last one
should contain graphic compression options. If the box next to "Used
compressed graphics" is clicked, unclick it to turn off compression.
Once this is done Click 'OK'. AOl 4.0 users have a 0-100 compression
option. Slide the bar down to 0 and then click 'OK' in the bottom, right
corner.
5.Compression should now
be turned off. Another problem with the AOL browser is that it will
not reload the graphics on a page once you have visited it with comressed
mode on. Once you have viewed an image incompresed mode, it is stuck
on your hard disk until you "clear the cache". To clear the
cache, go back to your "prefs" window and select the advanced
tab, and then select "purge cache". AOL 4.0 users may have
a empty or clear cahce option.
Option #2
(Use a better, 3rd party, browser)
America On-Line has improved
their browser's capabilities in version 4.0, however many of the same
problems that have made previous versions of AOL so infamous, are still
intact. Jpeg Compression, limited features, compatibility problems,
etc.
The best remedy to 95% of
these issues is to upgrade to a version of AOL with winsock capabilities
(aol 3.0 for win95, or AOL 4.0) and get a 3rd party browser like netscape
4.0-4.5 or Internet Explorer 4.1-5.0. With these versions of AOL, you
can download the latest Netscape or Internet Explorer versions (free),
and eliminate most if not all of these problems.
Once the new browser is installed,
run AOL, minimize it, and open your 3rd party browser. With the exception
of a few more features and more efficient loading, it functions similar
to AOL's browser.
Now you will be able to view
images the way they were meant to be seen. Use more convenient bookmark
systems. Also, when a 3rd party program uses AOL's connection, it keeps
it "active" which will eliminate the "idle" messages
that AOL constantly displays.
