Using the TeX Editor externally is generally not feasible, as LaTeX rendering typically occurs on the server side, and utilizing their resources for external purposes may not be permitted. Users can copy rendered images for use elsewhere, but should verify the legality of doing so. For alternatives, vBulletin's website provides insights into LaTeX rendering capabilities, and there are open-source platforms like WordPress that support LaTeX plugins. For generating images with TeX-like output, tools like the Codecogs Equation Editor are recommended. For document layout in LaTeX, users are encouraged to explore LaTeX software options, with additional resources available in related forum discussions.
