When creating an animation, file size is always a factor to consider. Dimensions, number of frames and other things can all affect file size. We want to keep file size as small as possible so the animation will load quickly on our Web page. The hearts we'll be creating are fairly large for an animated image, so try to select a pattern tile that has no more than 2-5 frames in the animation. More than that, and the final file size may be more than desired. The FlashLites website indicates the number of frames for many of their glitter patterns but other sites may not. You may have to open the file in Animation Shop to discover how many frames are used to create some glitter effects.
Open Animation Shop and the glitter pattern tile of your choice.
Make a note of the display time the pattern creator has used for each frame of the animation. Under every frame of the filmstrip it will say something similar to F:1 D:10. That indicates the frame number ( F ) and the frame speed/display time ( D).
If you don't see this information under the frames of the filmstrip, you will need to enable it by editing your "Preferences". Click File > Preferences > General Program Preferences. Under the Misc tab, check the box that says "Display frame count in window under animation".
Also, under the "Layered Files" tab, make sure you have checked "Keep layers as separate frames".
