Numerous (1000s) of PHP Notices Visible in Debug Mode

I just got finished giving this plug-in a 5-star rating – and am not in a mood to retract it, or my recommendations to others, but I happen to have just installed it on a development site with debug on, and have noted a very larger number of PHP Errors/Notices. I don’t know if they have anything to do with occasional functionality problems, but the main one, I suspect it gets repeated every time an image search is done, maybe on every item, is

Undefined offset: 0 in C:\xampp\htdocs\wordpressdev\wp-content\plugins\wp-inject\api.class.php on line 363

I’m also getting a smaller number of the following:

[15-Jun-2016 19:54:20 UTC] PHP Notice: Undefined index: pixabay in C:\xampp\htdocs\wordpressdev\wp-content\plugins\wp-inject\api.class.php on line 40

[15-Jun-2016 19:54:19 UTC] PHP Notice: Undefined variable: options in C:\xampp\htdocs\wordpressdev\wp-content\plugins\wp-inject\api.class.php on line 61

[15-Jun-2016 19:54:19 UTC] PHP Notice: Undefined index: json in C:\xampp\htdocs\wordpressdev\wp-content\plugins\wp-inject\api.class.php on line 278

[15-Jun-2016 19:54:20 UTC] PHP Notice: Undefined index: in C:\xampp\htdocs\wordpressdev\wp-content\plugins\wp-inject\api.class.php on line 185

also

[15-Jun-2016 19:52:44 UTC] PHP Notice: Undefined index: attr in C:\xampp\htdocs\wordpressdev\wp-content\plugins\wp-inject\wpdf_ajax.php on line 225

But mostly it’s that undefined offset notice: 1000s of them just today – with not a lot of usage!
