 * Hi, Thank you for a plug-in that solved exactly what I needed to do. Now I just
   need to make things prettier and could use your help. (& I have the latest version
   of DG.)
 * I’ve seen threads here on this but none that are quite helping me. My PDFs are
   just showing the generic icon. I’d love them to auto-generic “Fancy” which I 
   have checked in the settings. In lieu of this working, when I tried to replace
   that with something of my own I get this error message:
 * (DG_Thumber::thumbnailGenerationHarness) Failed to get image editor: No editor
   could be selected.
 * I do have Ghostscript supposedly, since it’s checked off in settings and has 
   an absolute path listed in Advanced settings.
 * And if this helps any, here’s my array code – thank you for your time!:
 * Array
    ( [thumber] => Array ( [gs] => /usr/bin/gs [active] => Array ( [av] =>
   1 [gs] => 1 [imagick] => [thumber-co] => )
 *  [width] => 200
    [height] => 200 )
 *  [thumber-co] => Array
    ( [uid] => [secret] => [subscription] => Array ( )
 *  [direct_upload] =>
    [mime_types] => Array ( )

 *  [gallery] => Array
    ( [columns] => 4 [fancy] => 1 [order] => ASC [orderby] =
   > menu_order [relation] => AND [limit] => -1 [mime_types] => application,video,
   text,audio,image [paginate] => 1 [post_status] => any [post_type] => attachment[
   descriptions] => [new_window] => [attachment_pg] => [skip] => 0 )

 * Hi sleepyhollowink,
 * That error suggests that you do not have the GD or IMagick PHP plugin configured
   on your server, at least one of which is required for WordPress (and transitively
   for DG) to function correctly.
