From within FSX you can use the "V" key, the screenshots will be saved to (in wins7) My Pictures/Flight Simulator X Files
as BMP's. You will need to convert them to JPG (use irfanview) to do this. BMP's are to big in size and is recommended
to use JPG's here at SOH.
To post them here:
When you either start a new thread or reply to a post, scroll down and you will see "Manage Attachments"
click on that and a new window will open, top right you will see "ADD FILES" a little window will open.
Click on "Browse" and go to where you have saved your screenshots, pick the pics you want to upload,
then click "UPLOAD". Once they are uploaded to the site, they will be attached to your post.
Another way is to use a free image hosting site like Photobucket. Using a site like this will allow the bigger
pics you see in the Screenshot thread.
