When I need a test image with specific size, I usually use picsum photos, it can be really helpful. If you use windows, you can put url directly into filename, so you can directly write "https://picsum.photos/width/height.png" and it will use random image from pexels. Really helpful.

I did this several days ago.
During the mock-up process in Web Dev, I frequently go to unsplash to get an image, download, copy to /images
, and resize. This does it all for me:
#!/bin/bash
function unsplash {
local FILENAME=unsplash-$(cat /proc/sys/kernel/random/uuid | sed 's/[-]//g' | head -c 10;echo)
wget -q -O $FILENAME.jpg https://unsplash.it/1920/1080/?random
echo $FILENAME.jpg
convert -geometry 450x $FILENAME.jpg $FILENAME-450w.jpg | echo
convert -geometry 800x $FILENAME.jpg $FILENAME-800w.jpg
}
unsplash
Generates names like this unsplash-bb16393268-450w.jpg
& unsplash-bb16393268-800w.jpg
.
I know there are other ways to generate a hash, but this works for me.
I was so excited, I started working on another one that uses the API from https://picsum.photos/v2/list
.
I've never really tried to do anything in bash, and this has been very rewarding :)

I really like that you can get a blurred version of the photo. I'd never thought to do that before, but would be so helpful to non-verbally convey "This is not a final image - it's a temporary placeholder!" I may start doing that in print pieces, too.
Also, this photo is great: https://picsum.photos/id/1025/4951/3301

My guess is because there are a lot percentages being used here.
One solution is to add a bit more width on your pseudo elements.
.slide-wrap:before, .slide-wrap:after { content: ""; position: absolute; top: 0; width: 51%; /* added 1% here */ height: 100%; transition: transform 5s linear; display: flex; align-items: center; background: url(https://picsum.photos/id/1015/1500/1500) no-repeat; background-attachment: fixed; background-size: cover; z-index: 2; }

I don't know of a program to do specifically that (most users want to see the images they download on the screen), but it's definitely possible. A good source for random images could be Lorem Picsum.

I was really hoping to find something similar to https://picsum.photos/
So I don't have to worry about actually sourcing pics, plus "https://picsum.photos/1280/720/?random" randomly generates the image.
Although what you say sounds like it would be good to try.
Maybe I can have it pull from an imgur album instead of keeping them local. But I would still have to source a bunch of pictures and I would rather spend my time working on the code.

How are you emitting the data through websockets?
Fetching a binary image and displaying it should be as simple as
const res = await fetch("https://picsum.photos/200/300"); const data = await res.blob(); const url = URL.createObjectURL(data); const imgElem = document.getElementById("image"); imgElem.src = url;
If the length isn't matching that means the data isn't being transafer correctly, have you inspected the ws requests?
