You can apply generic Male, Female, or Unspecified images to patrons if they don't have an individual profile picture attached to their record on the Personal tab of Patrons Management; pictures are assigned based on the gender value selected for each patron.
You can affix nearly any image supported by your browser (commonly accepted formats are JPEG, GIF, PNG, or BMP) into one of the three gender-based patron picture fields. If you don't have individual patron portraits assigned on the Personal tab of Patrons Management, these pictures will be used instead. Optimal image size for patron pictures is 186 pixels wide by 240 pixels high.
