Okay. Thanks to all your help I think (correct me if I'm wrong) that we've learned how to insert images into vm's, pm's, and posts. What we HAVEN'T learned to do (or even whether it's possible) is to resize images AFTER they've been inserted in a vm, pm or post. Yes, after insertion when I click on the image I do get the little square handles around the image. But when I click on them and try to tug the image and make it bigger, nothing happens. Does anyone know whether this has anything to do with one's browser internet settings? Anything to do with the way PC is set up? Why WOULDN'T one be able to change the size of an image on PC? Why would the image size handles appear, which they do, if one weren't supposed to be able to change the size of an image? Hmmmm.
Well, take care.

P.S. I have found out that one can shorten the process of image insertion by going into the browser's "Tools" area, clicking on "Internet Options," then on "Security," then on "Custom Level," and then enabling anything that has to do with scripting. Obviously only one single change should really be necessary, but since I don't know WHICH change is key I have to change everything to do with scripting. I'm running IE9. I do not know whether mac-users will have a similar thing but they may. Or any other browser. What this readjustment does is as follows: without the readjustment, when you click on the "insert image" button on PC, up comes a dialog box at the bottom of the page asking you if you want to permit scripted windows. If you click yes and then look for the insertion box at the top of the page, it isn't there. I've always had to click on "insert image" AGAIN and THEN insert the image location. If you change your settings, the insertion box comes up immediately and you can insert your image location then. Just a shortcut.
