Any way to search for transparent items?

Question

Is there any way to search for items that have an opacity of less than 100%?  I found that some of the advertisements I placed inexplicably came in at 76% opacity.  And I noticed some tiny endmark graphics came in with 0% opacity.  I don't know why.  I'm just trying to make sure I didn't miss correcting anything.
Thanks, Phyllis

Err, whoops. That's not going to work, because there's not a list of images in the document, only a list by page. And it's probably better to use Graphics instead, which include, e.g., PDFs.  So you probably want instead:
var d=app.activeDocument, im=d.allGraphics, i;
for (i=0; i<im.length; i++) {
  if (im[i].transparencySettings.blendingSettings.opacity < 80) {
    alert("Page "+im[i].parentPage.name+" has "+
      im[i].itemLink.filePath);
And this iterates over Graphics which are the things inside containers (like rectangles). You might have the transparency applied to the container rectangle instead, in which case you'd probably need to replace allGraphics with allPageItems, except then it would fail on all the objects that don't have a transparency property [sigh...], so you'd need something (ick) like this:
var d=app.activeDocument, im=d.allPageItems, i;
for (i=0; i<im.length; i++) {
  try {
   if (im[i].transparencySettings.blendingSettings.opacity < 80) {
      alert("Page "+im[i].parentPage.name+" has "+
        im[i].itemLink.filePath);
  } catch (e) { }
