When my dokuwiki pages are viewed using Firefox version 3.6.3 for Linux (Mandriva 2010.0 Linux), images are displayed with a line either under them (as shown here -
http://www.richardrandall.com/dokuwiki/doku.php) or to their right.(as shown here -
http://www.richardrandall.com/dokuwiki/doku.php?id=quality_manual#quality_manual).
The images are formatted as follows:
{{:insert_logo.png}}
and
{{:core_business_interactions_-_mfg.jpeg|Interaction between the processes of the quality management system}}
These images display fine when using Firefox 3.6.3 for Windows 7 and for Mac OS X version 10.6.3. These images also display correctly when using different browsers under Linux, such as "Konqueror" version 4.3.5 and "Opera" version 10.10 for Linux.
Because other DokuWiki pages (on other sites) display jpg and png files correctly when using Firefox 3.6.3 for Linux (on the same computer) I suspect that I must have something wrong with the syntax.
