how do i post pictures

Karen, hit "reply" and then hit "attach file" and then hit "browse."  This should bring up your computer''s photos.  Double click on the photo you want to attach.  If you get an error message, try renaming the file or make your picture smaller and then try again. 

If you try a pic once and it doesn''t load, definitely rename it before trying to post again. Even tho the pic did not load, the file name was entered into the PS system. The PS system won''t accept the same name for a file again.
 
As Patty said, sometimes pic files are too large. You might have to resize before posting and rename the file before loading.
