WordPress Theme Customization - Gallery sequencing & auto scroll

I have a WordPress theme and I need it customized. I would provide you with MySQL Database & WordPress files. You would need to develop it on your own dev server first, so I can preview and make sure it works correctly. Then, make it live on our live server... GALLERY SEQUENCING // Currently, each thumbnail is generated per post via Featured Image. The slider gallery within each post is generated via media upload (upload media, "save changes," and gallery is generated in "gallery" tab). Our desire is to link together all slider galleries from all posts in a specific category, so that a user can scroll through all images in that specific category from any post without having to click the "X" in the top right and navigate back to the homepage. Also, after having scrolled though all images in a specific category, the slider would then begin to pull images from the next category. For example, you click the first post on the homepage, which is in the "Beauty" category, and after scrolling through all images in the beauty category, the slider would show images from the "Editorial" category, "Red Carpet," and so on until all images have been viewed. This is the theme: [login to view URL] AUTO SCROLL // If you go to the link above, and if you make the browser window about 845px wide and 740px tall, you will notice the design is responsive. However, if you use the menu on the left, click "Filters" then "motion", you will notice no thumbnails are highlighted. This is because the first "motion" thumnbail is too far down the screen, making the user have to scroll to view. We would like the browswer window to auto scroll so if no thumbs are viewable from default window size, then it auto scrolls so the highlighted thumb is on top.
