Can't instal this addon

Hi 
After copying the files to the indicated locations I wanted to install the add-on.

It displayed the following information:

Deprecated: Creation of dynamic property sm_paczkomaty::$settings is deprecated in ~/includes/entities/ent_module.inc.php (Line 91) Fatal error: Undefined constant "WS_DIR_IMAGES" in ~/includes/modules/shipping/sm_paczkomaty.inc.php (Line 94)

Hey. Updated the module for the latest LiteCart version. Should be working now.
Please download the latest version and check. Let me know if it works

Yes, it works now. But i can set only one shipping cost and it is the Handling Fee.
[ol]
[li]What if a customer orders multiple products that need to be packed into multiple packages?[/li]
[li]Can you improve the add-on so that I can manually assign this shipping method to the products I select? That will help a lot.[/li]
[li]Also adding weight conditions will help will help scale shipping costs.[/li]
[/ol]

Now this shipping option is displayed for all products, even those that cannot use this option because they are too large or too heavy.
This add-on is currently only useful if the products in the store have shipping included in the product price and you offer free shipping.

Thank you for adding this add-on. "Paczkomaty" (Parcel lockers) are the most popular form of courier delivery in Poland, but the add-on needs to be more extensive to be useful.

Yes, I'm aware ;) I made this little extension just for my shop, and I only needed some basic options. If I find some time, I will try to add more configuration there
