A temporary fix that works 100 for now :
in the file ngx-gallery.umd.js changes this lines of code :

var CustomHammerConfig = /** @Class */ (function (_super) {
__extends(CustomHammerConfig, _super);
function CustomHammerConfig() {
var _this = _super !== null && _super.apply(this, arguments) || this;
_this.overrides = ({
'pinch': { enable: false },
'rotate': { enable: false }
