GRAND FlA Gallery users:
Beware: there is no simple way to edit the fonts you would like to use in the skins for this otherwise great plug-in. There are slideshow and color settings; but, nothing about fonts. When you charge for a plug-in, they should be fully editable, I believe.
This is what the plug-in author told me:
All flash settings are on Skins page - Options tab
You also can edit xml.php file but be carefully it's can break skin.
