Dynamic image displays depending on yes / no value

ok, i´ll give it a try this evening.

(I set the $status for testing to n - later i´ll read out the status of my light swithes in my home automation system... depending on the status I´ll show an image with lights on ...)

In the code that you show above, $status is explicitly set to "n" at the beginning (<?php $status="n";), so the conditional will always evaluate to the 'else' part - is that what you want?

All I get ist some text showing:   height="71" width="101" />

That's what you see on the page - those words in readable text? Try this -

<img src="stecker_<?php $status="n"; echo ($status == "y")?'on':'off'; ?>.png" alt="<?php echo $status=="y"?'yes':'no'; ?>" height="71" width="101" />
