below are patches for Users Guide, Options Help & lynx.cfg ,
adding explanations of the various choices for revealing/not images,
& moving VERBOSE_IMAGES to immediately precede the others in lynx.cfg .
please assess THE RENDERED HTML, NOT the source below.
i await the arrival of the piranhas ...

+ As a text browser, Lynx does not display images as such<br>
+ -- you need to define a viewer in <em>lynx.cfg</em>: see there -- ,<br>
+ but users can choose a number of ways of showing their presence.
+ <p>
+ There are 3 choices in <em>lynx.cfg</em>, with 2 corresponding keys:
+ <p><pre>
+ MAKE_LINKS_FOR_ALL_IMAGES * IMAGE_TOGGLE
+ MAKE_PSEUDO_ALTS_FOR_INLINES [ INLINE_TOGGLE
+ VERBOSE_IMAGES no corresponding key
+ </pre><p>
+ You can also use the Options Menu, as outlined below:
+ <p><pre>
+ key lynx.cfg FM LM .lynxrc variable in source
+
+ * MAKE_LINKS_ Y N N clickable_images
+ [ MAKE_PSEUDO_ Y N N pseudo_inline_alts
+ VERBOSE_ Y Y Y verbose_img
+
+ FM = new Form Menu ; LM = old List Menu ;
+ in .lynxrc , VERBOSE_IMAGES is called `verbose_images':
+ the other two cannot be saved between sessions.
+ </pre><p>
+ In the Forms Menu, the 3-way `Show images' selection<br>
+ combines the effects of the `*' & `[' keys, as follows:
+ <p><pre>
+ Ignore clickable_images = FALSE, pseudo_inline_alts = FALSE
+ As labels clickable_images = FALSE, pseudo_inline_alts = TRUE
+ As links clickable_images = TRUE, pseudo_inline_alts = unchanged

! (this is also switched by <A HREF="../Lynx_users_guide.html#[-key">'['
key</A>),
! <em>show labels</em> (see also "verbose images" for choice between [IMAGE]
and filename),
! <em>use links</em> for every image to make it possible to download them

comments
