I rather it say "image" then "false", especially if your picture says the "best pizza in town..." but hoovering over it, the website trying to promote it says "false"...
can I have an example of the <img> tag you mentioned, i see that there is the word "title" already, so i might be missing your reference
[code<img src="<?php echo $picture1_s5_iacf ?>" alt="<?php echo $title1 ?>" class="full" />
<img src="<?php echo $picture1_s5_iacf ?>" alt="<?php echo $title1 ?>" class="thumbnail" />
]
I hope it makes sense, that it would be counter productive to see anything that you are trying to promote say false
