Assigning smarty tag for product image alt

[Denver Prophit Jr.]

I'm building a module and need to access the value for product cover alt image [ 1 ] text. I thought it would be via 

$imagealt = Product::getCover()

But, I cannot find any documentation on the values I can pull from that function. Suggestions?

That only gets values from image_shop, while the legend (alt) is stored in image_lang. You need a custom query I believe

I'll test {debug}. Am not sure if the legend is already assigned a smarty global and how to pull that into my module? A documentation link or anything to read would help me learn.

Sadly, there is no docs for it. In the module you can just create a custom query, like normal SQL query, then use $this->context->smarty->assign
