176 PointsImage sequence
Looking to be able to scroll through a sequence of image using JQuery while the mouse is over the image. I have 61 images in a container div and have all of them hidden except one. I would like to use jquery to be able to scroll through the images only when the mouse is over the image.

230,688 PointsFor some reason this didn't work for me until I removed the "position: absolute;
" setting. It made sense that it didn't need it, as only one photo is visible at a time. But I still don't understand why having it on made nothing visible. Without access to the actual image files, I had to make up some but I wouldn't expect that to affect the operation.
Anyway, I was able to limit the scroll to only when the mouse was over the image container by adding this:
$("#container").on("mouseover", _=> document.body.style.overflow = "scroll");
$("#container").on("mouseout", _=> document.body.style.overflow = "hidden");

176 PointsThat solves part of my problem and thank you. I am still looking for it to only scroll through the pictures when the mouse is over the image, not scroll the page.

230,688 PointsBut your selection mechanism is based on window.pageYOffset
. Isn't the page scroll how your scroll through the images now?

176 PointsThat's the part I can't figure out and I'm sure it is an easy fix and right under my thumb. I don't want a page scroll but a scroll within the container div to scroll the pictures

230,688 PointsAre all the photos the same size? If so, you could do this in CSS with no JavaScript needed:
#container {
position: fixed;
overflow-y: scroll;
width: /* photo width + 20px for scroll bar */;
height: /* photo height */;
}
The container will have it's own scroll bar but be fixed on the screen.

176 PointsYes they are all the same size

230,688 PointsThat simple CSS should do the trick, then.
