1) If you scroll down about two inches below the "Submit Reply" button, there is another button that is called, "Manage Attachments" It's pretty self explainitory from there. You click browse then find the file where your pics are stored. There is a 620 wide by 280 high pixel max however. Plus a 19.5 kb file size limit.
An alternate method is to set up an account at a free photo storage place such as Photobucket. Once you load a picture, it will give you different options to post pics. Either just posting the link to your pics in Photobucket, using HTML tags to load the pic onto a website or using the IMG tags to post the pics on forums such as "The Gauge"
2) If you are crafty and good with your hands, probably with a little practice. However, buy some cheapies to work on your skill before painting the good stuff.
3) A lot of people swear by Woodland Scenics synthetic water stuff. (Jim being an exception here.

) Some have used clear silicone caulking. I saw a trick a guy did once using a mirror. This is where experimentation comes in handy. It's whatever suits you the best.
4) eBay is a great place to buy and sell if you use a little bit of caution. Check a seller's feedback to see what other buyers have said about them. If they've got a lot of negative complaints, it's probably best to avoid them. If they only have one or two negatives, check out the people that left those and see if they are only overly picky or have a ligitimate complaint. eBay has also started a new rating service for buyers to rate a seller on several areas of a deal rather than just the overall experience. You rate them on the accuracy of their description, their communication, their shipping time and the fairness of their shipping charges. A lot of people put eBay down but I've found some great stuff with a little bit of patience.
And I'm going to add a #5. And please do not take this badly because I mean no offense. You don't need to tell us you're a newbie in every thread title. We're all here learning together after all.
