Please don't roll your eyes, but is there any way to get the Tex to have the same background color as the forum?

You're rolling your eyes....I can feel it!

The tex images are transparent PNG

$$Jeepers! This is a perfectly transparent image!$$

If I'm not mistaken (which I often am (which is why I don't use my real name)) a transparent image allows you to select the "transparent" color. Set that color to match the background of
the forum and it would be wicked-sweet, eye-roller.

Are you using a current firefox or IE7 browser? It matches the background color for me.

It's not matching for me either. I have IE7 at work and the background looks white.

Oh sh********it! That means the problem is client side! I'm doomed. I'm using ncsa mosaic.

I mean lynx.

And at home? Could be a service pack thing. Both firefox and ie7 have support for transparent pngs

At work it could be the monitor filter.

Some of you folks are running IE7? Our IS department here at work has warned us off of upgrading so far. Something about problems with Oracle (which is a big part of our database infrastructure) and some other incompatibilities.

Guess I'll just have to see white backgrounds for a little longer. Maybe I can ping IS too see if they'll make an exception for me so I can spend more time at work on the PF. Errr, scratch that idea.:uhh:

It's current format, PNG, is 2200 bytes. A GIF of that same image is only 1700 bytes.

GIF's compression works best on limited colors. This is precisely the case. There are only two different colors. And GIF still retains perfect quality until you start using over several hundred separate colors. The advantage to GIF is that it is universally transparent. Even on older versions of IE, and other non-standard web browsers.

Newer is not always better. Why not stick with the old and try out GIF?

The main reason people don't use GIF anymore is because it's patented by Unisys, who threatened pretty much everyone with lawsuits. PNG was the worldwide community's response.

The transparent LaTeX images do not have just two colors -- they have approximately thirty, used for anti-aliasing. In general, PNG has superior compression versus GIF. The image you chose is not representative of all images.

Perhaps you should just put IE7 where it belongs and use a better browser.

That's easy to say, but the fact is something like 90% (I don't remember exactly) of Internet users still use Internet Explorer.

But I agree. If someone really cares about the transparency, he/she should get a better Web Browser.

The only images that showed correct for me were T4, T6, G4 and M1.

I'm running IE6.0.29 SP2 on WinXP2002 SP2.

For me,
on IE6.0.29 SP2 on WinXPHome2002 SP2,
T4, T6, G4 are close... but no transparency (no background stripes in the rectangle), fading to grey background.
M1 and M2 are correct.
All others are incorrect.

on FF1.508 on WinXPHome2002 SP2,
all images were shown correctly.
(I have no transparency problems there or on PF.)

Oh Lord, how quick they are to step into the footsteps of their enemies...

The reason why Firefox exists is because everyone hated the Microsoftian attitude of "Majority rules. Everyone else can go screw themselves."

So the rebels rise up and try to bring down the enemy. But do they make any positive change in the regime? No, they simply seek to replace the dictator with one that suits their own needs. Status quo.

Good one.

I could care less if MS was a dictatorship if only they made quality products. Firefox was more-or-less brought up because of MS's lack of concern on security and standards. It's scary when some 80% of users still use IE6 when it's nearly 6 years old! How long do we wait till we implement "modern" techniques and technologies. Firefox is not perfect, but it's much better than even IE7. Even Opera is a nice browser.
