$(function() {
    $("#popoverContainer").dxPopover({
        target: "#image",
        showEvent: 'dxhoverstart',
        hideEvent: 'dxhoverend',
        height: 300,
        width: 500
    });
});
<img id="image" src="https://www.devexpress.com/DXR.axd?r=9999_17-FD0Id" />
<div id="popoverContainer">
    <p>Popover content</p>
</div>
Angular
HTML
TypeScript
<img id="image" src="https://www.devexpress.com/DXR.axd?r=9999_17-FD0Id" />
<dx-popover
    target="#image"
    showEvent="dxhoverstart"
    hideEvent="dxhoverend"
    [height]="300"
    [width]="500">
    <div *dxTemplate="let data of 'content'">
        <p>Popover content</p>
    </div>
</dx-popover>
import { DxPopoverModule } from 'devextreme-angular';
// ...
export class AppComponent {
    // ...
}
@NgModule({
    imports: [
        // ...
        DxPopoverModule
    ],
    // ...
})
ASP.NET MVC Controls
Razor C#
@(Html.DevExtreme().Popover()
    .Target("#image")
    .ShowEvent("dxhoverstart")
    .HideEvent("dxhoverend")
    .ContentTemplate(@<text>
        <p>Popover content</p>
    </text>)
    .Height(300)
    .Width(500)
)
<img id="image" src="https://www.devexpress.com/DXR.axd?r=9999_17-FD0Id" />

If you need to position the Popover against a certain side of the target element, set the position option.

    $("#popoverContainer").dxPopover({
        target: "#image",
        showEvent: 'dxhoverstart',
        hideEvent: 'dxhoverend',
        position: "top" // or "bottom" | "left" | "right"
    });
});
