I'd like to include some basic math equations into a webpage. Is there an easy way of either compiling the LaTeX into an image which I can upload, or else of having the browser parse the code?

latex normally generates pdf, you can't put a general html/javascript page in a pdf file. So LaTeX isn't really an issue unless you are not using tex but one of the convertors to html eg tex4ht in which case it would be simple just to add the generated iframe to any html generated from the latex, but that isn't really a latex question.
Here's a possible implementation; the delimiters can be changed.
\documentclass{article}
\usepackage{amsmath,multicol}
\usepackage{xparse}
\ExplSyntaxOn
\NewDocumentCommand{\constraints}{omO{x}}
{
\IfValueTF{#1}{\begin{multicols}{#1}\centering}{\begin{center}}
\egreg_costraints:nn { #2 } { #3 }
\IfValueTF{#1}{\end{multicols}}{\end{center}}
}
\seq_new:N \l__egreg_constraints_seq
\cs_new_protected:Nn \egreg_costraints:nn
{
\seq_set_split:Nnn \l__egreg_constraints_seq { \\ } { #1 }
\seq_map_inline:Nn \l__egreg_constraints_seq
{
\__egreg_constraints_item:nn { ##1 } { #2 }
}
}
\cs_new_protected:Nn \__egreg_constraints_item:nn
{
\tl_if_blank:nF { #1 }
{
$#2\sb{\clist_item:nn { #1 } { 1 }} + #2\sb{\clist_item:nn { #1 } { 2 }}\ge1$ \\
}
}
\ExplSyntaxOff
\begin{document}
\constraints{
1,2 \\ 3,4 \\ 5,6
}
\constraints{
1,2 \\ 3,4 \\ 5,6
}[y]
\constraints[3]{
1,2 \\ 3,4 \\ 5,6 \\
1,2 \\ 3,4 \\ 5,6 \\
1,2 \\ 3,4 \\ 5,6 \\
1,2 \\ 3,4 \\ 5,6 \\
1,2 \\ 3,4 \\ 5,6 \\
1,2 \\ 3,4 \\ 5,6 \\
1,2 \\ 3,4 \\ 5,6 \\
1,2 \\ 3,4 \\ 5,6 \\
1,2 \\ 3,4 \\ 5,6 \\
}
\end{document}

mathURL is pretty cool. It's specifically for mathematics though.
