Multi-variable, combination-based dropdown lists

[jonsan32]

I want to list helpful instructions on my website for customers, specifically designed for them. I'd like for one of 16 images to appear below the 3 dropdown boxes, dependent on the values selected. The process can be instant or initiated with a submit button, but I'd like for the image space below to either be blank or defaulted as one image until all 3 options are selected. Is this possible? Any help would be great. Thanks!

<table border=3><tr><td> 
<table width=500><tr><td align="center">
I am <select name="players">
 <option value="0">- select an entity -</option>
 <option value="1">a coach or team representative</option>
 <option value="2">a player or parent</option>

</select>

</td></tr><tr><td align="center"> 
who would like to <select name="workouts">
 <option value="0">- select an action -</option>
 <option value="1">register</option>
 <option value="2">pay for</option>
</select>
</form>
 

</td></tr><tr><td align="center"> 
<select name="workouts">
 <option value="0">- select an option -</option>
 <option value="1">a FULL team (8-12 Players)</option>
 <option value="2">a PARTIAL team (5-7 Players)</option>
 <option value="1">a team member already on a team</option>
 <option value="2">an individual who needs a team</option>
</select>
</form></td></tr>
