There's also lilypie.com it's my personal favorite
For blinkies (like the PP mommy of angels blinkie) you can search for blinkies on the internet. If you can't find one you like, you can ask a nice person to make you one. I take requests but I like doing simple ones

To include counters/tickers (lilypie, tickerfactory, 3fatchicks) you go into your edit signature and include the code, which they will give you when you make your ticker, use the one with the [img] tages.
For blinkies I am copy/pasting from another post I wrote...
You download them to your computer and then upload them to a site like photobucket .com. Once you want to add them in to your sig, you put them in using the [img] tags.
You should never use another persons bandwith by taking their URL, you always need to save and upload to a new place (bandwith costs money)
So.. say you go to my site and want a blinkie..
1. right click and save it to your computer
2. get an account at photobucket.com and upload it to your account
3. edit your signature on here, using the [img] tag from the photobucket site
You can use the preview option when you are editing your sig to make sure it looks right.
