Can we make the full size image larger?

hello
is it possible to make the pop up image product larger?
maybe a % of the screen size that is responsive? 

which files and location is this found in ., thanks

Just upload a larger image. The max width displayed is 80% of the browser window (80vw).

thanks, but too many images to resize or upload

"The max width displayed is 80% of the browser window (80vw)" where is this located? it does not seem to be 80% at 1080p?

thanks

what im seeing is?

.featherlight .featherlight-content>img {
    max-width: 80%;
    max-height: calc(100vh - 80px);

Max width and width are not the same thing. Max width can be smaller, but no bigger than max.

Upscaling a low resolution image is rarely a good idea. It will not reveal any more detail.

i still dont understand where this change in made in the code?

im not sure if its right way, but this is what im using

[b].featherlight .featherlight-content>img {
    max-width: 80vw;
    width: 650px;
    max-height: 80vh;[/b]

seems to keep the popup image to correct dimensions 

i think if i use 100% or a % it means the % of the original image? so i need to define a larger size to force an upscale?

it seems to respond to the screen size changes ok

Remove max-width and set width to 100vw meaning 100% of viewport width.

hi tim, that will result in the image being stretched and distorted amd slightly outside of screen right

in
/ext/featherlight/featherlight.min.css
i added

@media (min-width: 768px) {
    .featherlight .featherlight-content>img {
        min-width: 500px;
        min-height: 500px;
        height: auto;
    }

so on bigger screens, small popup enlarge images open bigger than the thumbnail.
but on smalls screens original code applies
i should also allow larger images to load as per size?

With no max-wdth or a shrunken window your hi-res images will go beyond the width of the screen.

You could also try this:

.featherlight .featherlight-content>img {
        width: calc(100vw - 4em);
        height: auto;
    }

hi tim, that isnt working either? too big

could it be because im running dual monitors? 100% VIEW WIDTH is the total screen? not sure.
