Sleazy Fork

Browser: Brave Browser (based on Chrome. I also tried Chrome itself and the same thing happened)

Images are loading full size rather than scaled to window. However, I tried in Waterfox and it scales correctly.

Thanks.

What about a script manager? do you have TamperMonkey on your browser for userscripts?

Yes, I'm using Tampermonkey.

Works fine for me in Chrome + TM, make sure you have appropriate settings to scale images on load

and that you actually load image hostings and not images directly so the script would run

This is very strange. My settings match yours:

But Brave still acts differently to Waterfox. Take Instagram, for example. If I load one of the images from the page below in a separate tab:

In Brave it loads zoomed in:

In Waterfox it fits to the window:

In Brave, if I refresh the actual page so the script is running (https://www.instagram.com/p/CFakGSOF5eU/), the same thing happens and the image is zoomed in. However, if I directly copy the image link and load it (https://instagram.flhr4-2.fna.fbcdn.net/v/t51.2885-15/e35/s1080x1080/119993917_3551891071558893_8455624995516796141_n.jpg?_nc_ht=instagram.flhr4-2.fna.fbcdn.net&_nc_cat=109&_nc_ohc=KhTgj2Qob4oAX_8QGrp&_nc_tp=15&oh=8c84ae8903fba9e83c347d93421764e3&oe=5F96284C), it then fits to the window.

Any ideas?

if I directly copy the image link and load it

script doesn't run on directly opened images

Try Chrome (portable maybe) to see if it works there for you, if it does (it does for me) then the problem is in that chrome fork called brave

It does the same in Chrome. I've also just freshly installed Chrome Portable (no extensions or add on's other than Tampermonkey with Handy Image added) and it also does the same.

This is very unusual!

I thought I'd fixed it by changing the setting from "Larger than window both vertically and horizontally" to "Larger than window either vertically or horizontally", but it worked on that Instagram pic but didn't work on others (I guess it's because of the dimensions).

It does the same in Chrome.
