Alright, I dropped this in the image.php file and it worked:
`<?php if (hasPrevImage()) { ?>`
``
`[img]butt-prev.jpg[/img]`
``
`<?php } else { ?>`
`[img]butt-prevB.jpg[/img]`
`<?php if (hasNextImage()) echo ""; } if (hasNextImage()) { ?>`
``
`[img]butt-next.jpg[/img]`
``
`<?php } else { ?>`
`[img]butt-nextB.jpg[/img]`
`<?php } ?>`
It took me a while to figure out the syntax. Thanks though
