I just take a picture with my cellphone camera (hence, the bad but readable attachment).
I e-mail it to myself Then save it to my computer. When I reply or start a new thread (the Quick Reply box at the bottom doesn't give you an option to add an attachment, neither does the modify), I just click on the Attachment button and find where I saved it.
Easy as that.
Of course sometimes the pic is too big, so I have to save it a different way. Windows 7 has a Snipping Tool I use. Or you could put it in Paint and save it there. For some reason those are smaller files.
A good reason to read shorthand written by other writers: There's a wide variety, even among writers in the official books. So you will learn to decipher outlines better, including your own. when you write an unfamiliar word in dicatation or just writing, you will be able to transcribe it because you have learned how to read unusual outlines better.
"Gregg Shorthand had achieved the most extraordinary success ever attained by any system in the history of shorthand." John Robert Gregg, 1922
Worried your notes might not be good? Don't. This is gives you a chance to improve on your shorthand notes. I try to be kind, but honest. And maybe I may not be so kind and if I offend you I apologize, but sometimes it helps. In the Gregg Writer they use to have readers send in notes written from longhand and/or shorthand for a "test". Not all were good or even accepted, this letter is one that was rejected and you can see that the writer kept going and was doing fine.
If you didn't know, here's information on the OGA Tests.
This was given to teachers (quote from a 1973 teacher's book on Internet Archive archive.org/stream/ERIC_ED086788#page/n53/mode/1up ), but applies to all who reads the notes here or anywhere from "students" (unless, of course, the student wants correction or feedback and they ask for it):
