Progressive frame slider

if I can control volume by means of a slider , is there anything to stop me progressing through preloaded frames along a timeline with a slider? has anyone tried this? i am imagining giving the user control of a decaying image from beginning to end with the use of a slider?
does this sound the wrong way of going about this?
i am ok with actionscript but if anyone can help me out with this, i havent a clue where to begin!
