Feras from the web has asked me about creating SharePoint 2007 Themes that would appear in Arabic language.
Well, it should be similar to creating themes for English language, see Custom Site Theme for SharePoint 2007 (MOSS 2007) and WSS 3.0 under tigirry's SharePoint Blog but look for SPThemes.xml under 1025 folder instead of 1033. 1025 is the Locale Identifier for Arabic in Windows.
Happy Theme-ing!
