Where do I find my User ID #?

A user id number is just like a number you get on myspace. You're offered your url aka username and id number. Same deal with vampirefreaks, you have a username/url and a user ID number, you can get the ID number in many ways. The easiest two would be to; go to YOUR profile and click any of the contact buttons. In the url it'll show "uid=NUMBERS". You may also get your user ID through your pictures, simply go to your gallery, click any picture, and once again in the url it'll say, "uid=NUMBERS". Now all you need to do is save that number, and you can use it for layouts. :]

I want to add music to my music section, do you know any good sites for music players?

Personally I use http://www.myflashfetish.com/ it's a great site, because you can customize your music 
player to fit your new layout, and you can also make your own playlists, which can set to shuffle, 
so you're not stuckwith the same song every time someone loads your page!

How do I make image links?

Here's the code you need to make your own image links. Just fill in your info and it should work fine. Do not leave out the "http://" bit or it won't work.

I keep trying to get a vf picture to show up when I make image links, why won't it come up?

Either the picture has been deleted OR you're using the wrong link. It's an easy mistake, and easier to solve. To make sure you're using the right link, go to the picture you want to use in the gallery, then right click the picture and select "open in new tab/window". This should take you to the proper link.
