hi, David
I did something like this, but still not working!!!

pro read_several_png
cd,'D:\p\'
pathName="D:\p\"
List = findfile(pathName+"*.png")
nosFiles=N_ELEMENTS(List)
data = ptrarr(nosFiles)
outfile = STRARR(nosFiles)

for i = 0, nosFiles - 1 do begin
x=read_png(list[i],rpal,gpal,bpal)
rootname = File_Basename(list[i], '.png')
data[i] = ptr_new(x)
endfor

ps_start, pagetype='a4'
!p.multi=[0,3,9]
for j=0,26 do cgimage, data[j]
!p.multi=0
ps_end
end
