How to pass PS variables to module

[VladimirKon]

In the first module i can't manage to display thumbnail image in my module using code from product.tpl . For example if i copy-paste code below to any place (under 'condition' for example)  in product.tpl it show last thumbnail image. But when i copy-paste code to my module there is no image. 

<img src="{$link->getImageLink($product->link_rewrite, $imageIds, 'cart_default')|escape:'html':'UTF-8'}"/>

 

My module hook is 'rightColumnProduct' and {debug} says $imageIds is not assigned. 

 

Module 2.

Module hook: displayProductTab / displayProductTabContent

I want to move all customization options to custom tab on product page and move all code related to customization to mymodule.tpl. Select and radio option(Size/Color ex.) works good but i can't move textfield to my module. 

i have {debug} in mymodule.tpl and $customizationFields variable have no values and it's not assigned. 

 

My modules displayed on the product page why they do not receive values from product.tpl?

How can i pass ALL prestashop product page variables to my module? 

Thanks.
