Error when no picture added (we tested if user will not add picture)

ERROR:

    $img_uploading = count($aItem['photos']['name']);


Lines 1738-1748
function osc_redirect_to($url, $code = null) {

@aroca
Well that is interesting, as PHP control should never be activated on site without errors.

As I cannot replicate problem, PM me login to your ftp & oc-admin.

@aroca, @sachinthana
I think I have identified problem.
To fix, please go to file:
oc-content/plugins/image_required/index.php

Find code (there are 2 occurences):
    $img_uploading = count($aItem['photos']['name']);
    $img_count = $img_exists + $img_uploading;

Replace with (both of them):
    if(array_key_exists('name', $aItem['photos'])) {
      $img_uploading = count($aItem['photos']['name']);
      $img_count = $img_exists + $img_uploading;
    } else {
      $img_count = 0;
    }
