My images are not showing

Rok,

I did some further digging.

The issue seems to be in your function wp_rp_get_image_data as part of the thumbnailer.php.

The checks:

if (!$imagedata || !is_array($imagedata) || !isset($imagedata['sizes']) || !is_array($imagedata['sizes'])) {
		return false;
	}

Are failing, in particular the checks around $imagedata[‘sizes’]. I dumped out the $imagedata array and found that the image meta data is missing the sizes array, even after I regenerated the thumbnails. I also tried to remove the Featured Image and re-upload but still the Thumbnails would not work.

I suspect the issue might be environmental, or in the WordPress core… We have a test site where the plugin is working. The main difference between the two sites is one is an a shared hosting the other is an AWS instance.

Regards
Michael

Just a follow up on this.

The meta data for images loaded into the Media Library were not being set.

If we do a:
print_r (wp_get_attachment_metadata(ID));

Where ID is the ID of the image from the Media Library.

All that is returned is:
Array ( [width] => 506 [height] => 339 [file] => 2013/08/122399110.jpg [image_meta] => Array ( [aperture] => 0 [credit] => Getty Images/Ingram Publishing [camera] => [caption] => Close-up of a cup of coffee near a newspaper pen and eyeglasses [created_timestamp] => 0 [copyright] => [focal_length] => 0 [iso] => 0 [shutter_speed] => 0 [title] => 122399110 ) )

On the test site all of the meta data was being displayed.

In looking further we found that we did not have GD or Imagick installed. Once they were installed and I regenerated the image Thumbnails – using Regenerate Thumbnails plugin the meta data was available. After about 30 seconds the images started to appear for the Related Posts plugin.
