i think it just means u can load a image from an atlas image and use it for the particle emitter.
here a example from me how to use loadsubimages.
rem AGK Application 1.08 Beta 19
rem MR 21.10.2013
SetDisplayAspect( 4.0/3.0 )
//--------------------------
MainLoop()
end
//--------------------------
function MainLoop()
//my atlas image
//3 rows each 8 images = 24 subimages
//image witdh = 512 / 8 = 64 pixels
//64x64 one image
dim img[24]
imga=loadimage("animals.png")
for i=0 to 23
//each line line in "animals subimages.txt" = imageName:X:Y:Width:Height (ignore //)
//img0:0:0:64:64
//img1:64:0:64:64
//img2:128:0:64:64
img[i]=LoadSubImage(imga,"img"+str(i)) //get one image by virtual image name in "animals subimages.txt" file
next
//-------------------------- dummy sprite for width & height because display aspect
spr=createsprite(0)
setspritesize(spr,10.0,-1) //-1 = automatic height
w#=getspritewidth(spr)
h#=getspriteheight(spr)
deletesprite(spr)
//--------------------------
//-------------------------- some sprites on screen
i=0
for y#=0.0 to 100.0-h# step h#
for x#=0.0 to 100.0-w# step w#
spr=createsprite(img[i])
setspriteposition(spr,x#,y#)
setspritesize(spr,w#,h#)
i=i+1
if i>23 then i=0
next
next
//--------------------------
do
if getpointerpressed()=1 then exit
Sync()
loop
//--------------------------
//... free ...
undim img[]
deleteimage(imga)
endfunction
