That's OK... You should be able to do something along the same lines with PE9... I have a PE7 copy and have just checked it out.
If you go to FILE then 'Process Multiple Files' you will get a window up showing things you can edit - size is one of them and it looks fairly similar to that in CS6. There should also be a little "Help" icon [light bulb] at the top of that window with a link to the help files to learn more about "Process Multiple Files".
I feel the difference is the "Quality" setting. If Paint has an area to specify "quality" then that needs to be a lower figure than a higher one - 10 or 12 is the highest setting and therefore a larger FILE size... not image size; you can have an 800 x 533 pixel image that is a different 'saved' file size like 132 Kb or over 200 Kb - - - which is what Flickr is doing... changing your uploaded "file" size not "image" size.
No worries about being a 'learner'... I'm learning new stuff most days depending on what it is I'm trying to do
Adobe have lots of free training videos on line for their programs so give them a try also. I doubt I will use a fraction of what CS6 or Lightroom - or even PE7 for that matter - of what they are capable of being able to do. I'm thinking of trying to do a course at a college after I retire [in March 2016] and see if I can earn a bit of cash giving lessons on these programs - - - wishful thinking
Have fun... I'm sure you'll be able to do with PE9 as I've found I can with CS6 - which was thanks to a 'free' training video link from Karl Taylor
oops! that's PHOTOGRAPHY ... worth checking out
