Q1 This is done in the Export Dialogue box. Select images to be resized/exported. Enter the various parameters and also the destination folder. Then click OK.
It is possible to export direct to the web, but have no idea how you would set up your own web page. but it's extremely easy to export to such as ProShowGold, Facebook or Flickr, but You will only be able to export as either Jpeg or Tiff, but not simultaneously.
