Code editor and snippets

Any advice for a choice about a code editor with a snippets library ?

I have tried smultron it is free with a lot of features but it don't accept image copy in snippets...and for learning code i have to capture images because i am a visual person...:)

the one of my dream would have these features : support : ( in priority order) html, xhtml , css, javascript, objective c, c, core image kernel, glsl, opengl.

And a snippet library with text and image support.

Thanks.
