1. Make your animation.
2. Save your animation as a GIF (select .gif instead of .piv from the drop-down menu).
3. Uncheck "Crop" and "Merge," and set the frame delay to:
7 if your animation plays best with the slidebar at the bottom
5 or 6 if it plays best with the slidebar at the middle
4 if it plays best with the slidebar near, but not at, the top
3 if it plays best with the slidebar very near, but still not at, the top
2 if it plays best with the slidebar at the very top
4. Go to
VuloMedia. THIS IS THE BEST IMAGE HOSTING SITE. EVERYBODY IS FORBIDDEN TO DENY THIS. I MEAN, COME ON, IT DOESN'T HAVE ANY POPUPS OR BANNER ADS, THE SERVER IS REALLY FAST, THE FILESIZE LIMIT IS REALLY BIG, IT DOESN'T RANDOMLY LOSE YOUR IMAGES, AND THE IMAGES UPLOAD IN LIKE THREE SECONDS. THAT'S PRETTY FREAKING GOOD. SERIOUSLY. I SHOULD STOP TYPING IN ALL CAPS.
5. Click on Browse and find your GIF. Double-click on it, or click "Open," whatever floats your boat.
6. Click on Upload. Wait until it uploads.
7. Copy and paste the image URL into [img] tags.
8. Post the freaking animation already.
Oh, one other thing: VIEW ANIMATIONS IN FIREFOX! Internet Explorer sucks at GIF images and it makes them randomly lag and likes to screw up their framerates.
