Texifier’s live typesetter does not support rendering EPS files.
If you want to typeset vector graphics, please export them as PDFs rather than using the EPS format. PDFs can be included the same as any other graphics file, using the graphicx package, and the \includegraphics{} command.
The Windows variant of this article will be updated in due course. To try out Texifier for Windows before it is publicly released, please sign up for a beta.
