Personally I prefer to use the screenshot key ingame, check your preferences to find it, I changed mine ages ago and forget what the default key is.
It will appear as a .png file here - C

Just double click it and save as .jpg to lower the size of the file.
Then upload it to an image host...........etc.
I do it this way so I can take quick pic of anything I want during the game and then sort and/or delete later. It also keeps a good record of how your career has panned out.
