You can write in PageA.PageA one among:

  Attach:GroupA.PageA/image.jpg
  Attach:{$FullName}/image.jpg

Then the image will be displayed in both PageA and PageB.

(The solution to use Attach:{$Group}./image.jpg will work for wikis with the  
default $UploadPrefixFmt, not for you; this solution here should work in  
both cases of $UploadPrefixFmt.)

It is possible to instruct PmWiki to automatically insert GroupA.PageA when  
including a page. Something like this in config.php may work:

  SDV($QualifyPatterns["/(\\[\\[ *Attach:)([^\\/$UrlExcludeChars]+(\\|.*?)?\\]\\])/"],
    PCCF("\$m[1].\$pagename.'/'.\$m[2]", 'qualify'));
  SDV($QualifyPatterns["/\\b(Attach:)([^\\s\\/$UrlExcludeChars]+(\\s|[$UrlExcludeChars]|$))/"],
    PCCF("\$m[1].\$pagename.'/'.\$m[2]", 'qualify'));

This has not been extensively tested but should work in most cases for most  
attachments (pictures or not) in included pages.

Maybe I should create a Cookbook recipe and let people test the snippet so  
we can improve it before eventually include it in the PmWiki core?
