Product pics not coming after latest upgrade

-
i am getting Following Issues
- Not getting Product Listing when clicked on a category from the Online Shop Module created in Hikashop
- When i click on some categories pics are not coming its showing some error with referance to the image.php file in helpers folder in admin, i checked the forum its showing old remedy i have just upgraded to the latest version available and this error started coming after the upgrade. .
- another query about using the same links as we get from the menu instead of creating different links from different modules, i mean cant we use already created menu links instead of creating new for the product displays from different modules catgegory links
- cant we have product options drop down instead of a button for options taking us to products page

Hi,

1. Thanks to check if you have an associated module listing products to you category menu in the hikashop menu options
2. The error can help us to debug this.
3. In the options of the modules, you can select the same menu, even if it's different categories.
4. By default, no. You will have to make view overrides, and probably some more queries.
