Just go to file>Batch Converstion/Rename check mark the use advanced option and click on the advanced setting button and select the width and height. Then select the folder and drap it to the Input window and say start with in seconds all your images will be resized you can get irfan view from any of the digit cd's DVD's.
figured out in PS.. it was in the file menu, i forget which option.. will tell that after I reach home...
u can make any action and apply it to a whole batch.. the compression was really good too..
