Slicing an image

Question

For a project I am working on, I would be like to be able to slice a photograph up into a number of smaller segments. I can explain what I want to do best in terms of what this would look like if I were working with a physcial print.  Let's say the print is 8 X 10 inches.  I'd like to take that print and cut it up into 16 half inch strips along the 8 inch side, and then cut those horizontally into 20 half inch little squares.  It would sort of resemble a jigsaw puzzle but of course all the side would be straight.  Is there a convenient way to do this in photoshop? I'd want to be able to remove these and rearrange them in PS or perhaps paste each segment into inDesign or Quark.
Thanks.

You can do this with a script ...
#target photoshop
function main(){
var dlg=
"dialog{text:'Script Interface',bounds:[100,100,380,290],"+
"panel0:Panel{bounds:[10,10,270,180] , text:'' ,properties:{borderStyle:'etched',su1PanelCoordinates:true},"+
"title:StaticText{bounds:[60,10,220,40] , text:'Tile Picture' ,properties:{scrolling:undefined,multiline:undefined}},"+
"panel1:Panel{bounds:[10,40,250,130] , text:'' ,properties:{borderStyle:'etched',su1PanelCoordinates:true},"+
"statictext1:StaticText{bounds:[10,10,111,30] , text:'Accross' ,properties:{scrolling:undefined,multiline:undefined}},"+
"statictext2:StaticText{bounds:[140,10,230,27] , text:'Down' ,properties:{scrolling:undefined,multiline:undefined}},"+
"across:DropDownList{bounds:[10,30,100,50]},"+
"down:DropDownList{bounds:[140,30,230,50]}},"+
"button0:Button{bounds:[10,140,110,160] , text:'Ok' },"+
"button1:Button{bounds:[150,140,250,160] , text:'Cancel' }}};"
