I am trying to get the function ImagesR, which checks for occurrence of any one of three images, to work.

This is what I have in the ss template:

<% if ImagesR %>
<img width="$ImageWidthR" src="<% control ImageR.SetWidth(280) %>$URL<% end_control %>" alt="$AltTextR" title="$TitleTextR" />
<img width="$ImageWidthR" src="<% control ImageR2.SetWidth(280) %>$URL<% end_control %>" alt="$AltTextR2" title="$TitleTextR2" />
<img width="$ImageWidthR" src="<% control ImageR3.SetWidth(280) %>$URL<% end_control %>" alt="$AltTextR3" title="$TitleTextR3" />
<div class="caption"><p><i>$CaptionR</i></p></div><% end_if %>
<% end_if %>

This is what I have in Page.php
class Page_Controller extends ContentController {
...
function ImagesR() {
return ($this->ImageR || $this->ImageR2 || $this->ImageR3 );
}

It doesn't work. It works if I pass non-image arrays (e.g., $this->CaptionR), but not apparently with images.

Is there a trick for creating an OR function for images (e.g., class Page_Photo extends Image)?

I don't get it?

I tested this and to my amazement this worked: I did create an Image2 in my template, but how should I know that this also includes the creation of an Image2ID? Image2()->ID I can understand. Or should I know this - and is this just me being a N00b?

For the record: I compared what the Image2() returns with or without an Image, and noticed that for instance a Title was present when there actually was an Image2 on a page. Testing for Image2()->Title should therefor enough of an indication that there is an image. (Of course this could change in future releases.)

Therefor I tested with just $this->Image2()->ID and with just Image2()->exists(), and they both give me the right result. Why the double testing? (I would prefer the Image2()->exists())

return print_r(ImageR()) always returns something, but only when there is an image in it, it returns data about the image. So you have to check if the image exists.
