Hello,
Flags are coded in a web part, so if you want to hide them, please duplicate the
Language selection drop-down web part and comment or delete following lines from its source code:
175: imgFlagIcon = this.GetImageUrl("Flags/16x16/" + HTMLHelper.HTMLEncode(culture.CultureCode) + ".png");
295: imgFlagIcon = this.GetImageUrl("Flags/16x16/" + HTMLHelper.HTMLEncode(cultureCode) + ".png");
Best regards,
Jan Hermann
