Umm, that isn't what I was expecting. What that gave me was a bulleted list of links of all the images associated with each record.
Let me see if I can be clearer. I am displaying the main image on the show.php page. I am displaying it at a smaller size than the full size image using the max-width and max-height attributes in the css. However, I'd like a person to be able to click on that displayed image and get the full size image in a new browser window. So, essentially what I want is this:
<a href="full_size.jpg"><?php
if(item_fullsize()) {
echo item_fullsize();
}
?></a>
But I don't know how to do that in php using Omeka's nomenclature.
