Yes, this is totally possible, but not with the images (that I am aware of). I use it as a chart, and works like a charm for me. Here's what I have for the seating chart: <seatingchart format="diagram" showEmptyTables="true" columns="2" showHits="false">
For buttons, I apologize for how this may look, but this is what suits my needs:
<tdbutton type="SelectScreen" modifier="1" text="Main Screen" inheritFont="false" link="false"><tdbutton type="SelectScreen" modifier="2" text="Rankings" inheritFont="false" link="false"><tdbutton type="SelectScreen" modifier="3" text="Season Points" inheritFont="false" link="false"><tdbutton type="Save" inheritFont="false" link="false"><tdbutton type="AddPlayers" text="+ Player" inheritFont="false" link="false"><tdbutton type="NewPlayer" inheritFont="false" link="false"><tdbutton type="BuyIn" text="Buy In" inheritFont="false" link="false"><tdbutton type="NextRound" text="+ Round" inheritFont="false" link="false"><tdbutton type="PreviousRound" text="- Round" inheritFont="false" link="false"><tdbutton type="BustOut" text="Player KO" inheritFont="false" link="false"><tdbutton type="UndoBustOut" text="Undo KO" inheritFont="false" link="false"><tdbutton type="Clock" text="Pause/Unpause" inheritFont="false" link="false"><tdbutton type="SetClock">
What I suggest, is to use the "Insert Token", and select tdbutton (scroll to the bottom to see it). From there, you can easily select what you want and how you want it. I suggest leaving the inheritFont as false, and if you want a true button, leave the link false, whereas if you want it to show as plain text, then make the link be true.
Hope this helps!
