Barand Posted January 2, 2008 Share Posted January 2, 2008 $white_ex = ImageColorTransparent($dst_ex,$white_ex); the above sets $white_ex to the previous transparent color (none), use ImageColorTransparent($dst_ex,$white_ex); ImageColorTransparent($dst_med,$white_med); ImageColorTransparent($dst_small,$white_small); Quote Link to comment Share on other sites More sharing options...
