Hey Elroy,
first of all, thank you for the purchase and the kind words!
I will go over your questions in the same order:
1). Could you please clarify which tile you have in mind? I’m not sure I can see one entitled “portfolio” or with a portfolio image. Thanks!
2). Again, I’m afraid I will need more information – do you mean the masonry tiles which have images in them or something else? Do all tiles not work or only some specific ones?
3). This will require some modifications: please use these custom files I made for you; they should go into the theme folder, replacing the existing ones. You can use them in the parent theme folder since if this works I will include the code into the next theme version (3.1) as well.
Sincerely,
Andrii / Satori Studio
