Dear All
I need the unix program “dvipng” to render latex math on my page. dvipng it is not present on my server is there any equivalent tools?

This came up just last month in this very forum:

I followed the hints in the post but after putting the excutable in my bin dir I got the following error:

TWiki detected an internal error - please check your TWiki logs and webserver logs for more information.

exec failed: Permission denied path

If you are trying to set up MathModePlugin for TWiki you’ll need to give execute permission to latex2img:
