Hello @defthaus,
Thank you for the clarifications. Regretfully this is the default behaviour of the lightbox. The image will be stretched to cover the lightbox area. There is no setting in the grid to reduce the maximum width to at least 2500 pixels instead of 100%. Changing the maximum width by way of custom css such as like this:
.esgbox-slide .esgbox-image-wrap img{
max-width: 1200px;
height: auto;
}
could lead to a further layout issues. Please keep in mind that custom coding beyond the scope of our support. Issues that might arise from the use of custom code and further enhancements should be directed to a third party developer.
Thank you for your understanding.
