Dummy Urls give broken images

Hello Guys,

I recently updated this plugin to version 2.4.1 , and suddenly (no immediately), I could not upload images anymore. All of the uploaded images give a broken image thumbnail.

When placing the link on the browser I get a NOT SUPPORTED message.

Example image URL after plugin update NOT OK: https://androidgeek.pt/wp-content/uploads/gdwpm_images/0B5CUt-KUpXFUeF9jckNVaW9vQ0k.jpg

Example image URL before plugin update OK: https://androidgeek.pt/wp-content/uploads/gdwpm_images/0B5CUt-KUpXFUbzdpaHlBZ3ZWUmc.png

After trial and error, I found out that disabling the dummy URL option, would solve the problem. But I really need this option working.

Is there any change needed on the .htacess or index.php file in “gdwpm_images” folder?

Thank you for your help
