Lightbox behavior on packery and single item page

Good morning,

At the begginning I'd like to thank for a cool and prisewise extension.

Although I've got a question and asking for help in modifying Your code (If You don't mind of course

Since I can't insert screenshots in here, I'll put links showing the problem.

How could I switch the way the lightbox enlarges photoses at packery (half-width layout):

luminart.com.pl/packery-item-lightbox.jpg

to this way of lightbox (single item page)

luminart.com.pl/single-item-lightbox.jpg

On the project I'm working now, there is no need to have an extra page for each item.
All I need is simple gallery but on that layout lightbox enlarges pictures to some default size, making them look different than oryginal.
And scrolling appears.

But when you use different setting of Juxportfolio with pages for each items, the lightbox on that single pages works fine (even though the picture appears on left side). The photoses appear correctly according screen-size and stay sharp with no scrolling.

So I figured out that on packery layout I could use the same link (settings) to open pictures as on a single page item.

I'm not a programmer but I'm not affraid to look at the code

so If You understood my inquiry and be so kind I would be happy if You point me out where to look? Or give me any suggestion.

Thanx

Tomek

Thank You HaiND for Your work. Appreciate this. It's saved me a lot of time looking into the code, as I'm not a programmer

all the best to You and JoomlaUX
