Hello!
   
  When I tried to save some photo files
  from SAVE AS menue
  " ???????????? " (many question marks) appeared to the file type box and those files were not able to be opened with powerpoint or paintnet, only opened with IMAGE J.
  Original file was made with Macintosh photoshop. I used  windows XP after that.
  Does anyone have any idea what is wrong ?
   
  Recently I asked about resize function of IMAGE J.
  I found I can only change pixel number.
  What I want to do it to resize big file size photo like 1-2MB to 500kb photo file.
  Is that possible ?
  I know I can do that with photoshop, but currently I do not have PC version of photoshop.
   
  I would appreciate any help.
  Thanks.
