Posting pics is easier than you think--don't be intimidated, just have fun! Take the picture, then file it somewhere on your hard drive. Go to
https://imageshack.us/ and click on "Browse," then navigate to the folder on your hard drive that contains the picture and select it. If the selected picture is too big, you can choose to resize it automatically. The picture will then be uploaded from your computer and placed online. You will be shown a results page with several links to the website you just created that holds your image.
On the results page, there will be several options available. If you copy the "Direct Link" information, you can paste the photo directly into your post here by first clicking the little photo icon in the toolbar, then pasting the copied text. If it is a really big picture, it is bad form to use the direct link posting option, and you can instead have mercy on those with dialup and use the "Thumbnail for Forums" option. With that, you can copy and paste straight into your post without using the toolbar, and in the resulting post, there will be a nicely sized preview image that viewers may click and be taken to Imageshack for the full size version. Play around with it and you will find that it's not as hard as it seems!
