if you already know how to do the property tweaks, but want to figure out how to do it on a
picture you imported just convert the pic to a graphic or movie clip (F8)
If you want to know how to just do property changes in general, read below (and hopefully Ill tag what you were looking for
)
if you want to have it gradually change: create keyframe @ frame 1 (or whenever you want the change to start) and then another keyframe however many frames later (ex. 30), go to the first of those keyframes, right click --> create motion tween. Go back to second keyframe, and click on your purty little graphic on the stage:
if in MX: change the properties on the properties bar (normally at the bottom), color = (whichever you want, or advanced for combinations)
earlier than mx: right click, properties, change the color stuff from there
should work after that
...if that had nothing to do with what you were asking, I apologize
