A LaTeX-tag would be cool:

$e^{i\pi}+1=0$


This would be displayed as:

Wow, brings back memories. I used to know TeX by heart and a good amount of LaTeX as well. I was in college when it first came out. This one lady at the computer center was just gaga over it.

Another consideration may be MathML. I thought it was dead but it looks like they just updated it...

Perl is a unix routine. How do I run that on my wodoze machine?

You may install strawberryperl or activeperl. Use a file for the formula instead of the here-document:

perl -MURI::Escape -ne 'chomp; printf "[img:http://latex.codecogs.com/png.latex?%s]\n\n", uri_escape $_' formula.txt  There might be other utilities to uri-escape. HTH Thomas I can't test that right now, but the following should work. Create a file "uri-escape.pl" with your favorite text-editor and enter the following lines: use URI::Escape; while (<>) { chomp; printf "[img:http://latex.codecogs.com/png.latex?%s]\n\n", uri_escape$_;
}


Create a 2nd file "formula.txt". It may contain several formulas each on a separate line:

e^{i\pi}+1=0


Now run in a command prompt:

perl uri-escape.pl formula.txt


If you are too lazy to upload images you can use aamath for "a-text":

$echo "e^(i*pi)+1=0" | aamath __ i || e + 1 = 0$ echo "sum([n-1;r],r = 0 .. min(n-1,4))" | aamath
min(n - 1, 4)
=====
\         / n - 1 \
>        |       |
/         \   r   /
=====
r = 0
