[LinuxCNC/linuxcnc PR#190] fix docs/2.7/2.8 add img alt

#1 – SebKuzminsky 于 2016-10-23

Are these commits intended for master or 2.7?

#2 – tseufl 于 2016-10-23

@SebKuzminsky
for 2.7 and 2.8 (master).
at the moment, all the image-alt-tags in the docs on the website contains the path and filename.
Example: view-source: http://linuxcnc.org/docs/2.7/html/user/starting-linuxcnc.html (line 61).
For the image-alt-tag is not intended as used at the moment …

In the asciidoc-engine you could probably turn off (path and file name in image-alt-tag) but currently (2.7) and for the future (2.8) should be the image-alt-tag-attribute for seo [search engine optimization] use…

Consistently, it would have to actually go back to the oldest available html version which uses images in the docs …
