How To Attach A Log File?

I cannot figure out how to attach a log file? The only file I am allowed is an image file (jpg)??

We no longer allow log files to be attached to the forum (over the years it became very expensive for us to allow it). Instead we have come up with an even easier way to report issues with logs.
