These two reasons is largely why ion-img was created. The standard HTML img element is often a large source of these problems, and what makes matters worse is that the app does not have fine-grained control of requests and rendering for each img element.

The ion-img component is similar to the standard img element, but it also adds features in order to provide improved performance. Features include only loading images which are visible, using web workers for HTTP requests, preventing jank while scrolling and in-memory caching.

Note that ion-img also comes with a few more restrictions in comparison to the standard img element. A good rule is, if there are only a few images to be rendered on a page, then the standard img is probably best. However, if a page has the potential for hundreds or even thousands of images within a scrollable area, then ion-img would be better suited for the job. Note: ion-img is only meant to be used inside of virtual-scroll.

Lazy loading images refers to only loading images which are actually visible within the user's viewport. This also means that images which are not viewable on the initial load would not be downloaded or rendered.

Next, as the user scrolls, each image which becomes visible is then requested then rendered on-demand. The benefits of this approach is that unnecessary and resource intensive HTTP requests are not started, valuable bandwidth isn't wasted, and this allows the browser to free up resources which would be wasted on images which are not even viewable. For example, animated GIFs are enourmous performance drains, however, with ion-img the app is able to dedicate resources to just the viewable images.

But again, if the problems listed above are not problems within your app, then the standard img element may be best. By providing image dimensions up front, Ionic is able to accurately size up the image's location within the viewport, which helps lazy load only images which are viewable. Image dimensions can either by set as properties, inline styles, or external stylesheets. It doesn't matter which method of setting dimensions is used, but it's important that somehow each ion-img has been given an exact size.

By giving each image an exact size, this then further locks in the size of each ion-itemwhich again helps improve scroll performance. Additionally, each ion-img uses the object-fit: cover CSS property. What this means is that the actual rendered image will center itself within it's container. Future goals are to place image requests within web workers, and cache images in-memory as datauris. This method has proven to be effective, however there are some current limitations with Cordova which we are currently working on.

Sets the bounding rectangle of the element relative to the viewport. When using VirtualScrolleach virtual item should pass its bounds to each ion-img.

The passed in data object should include top and bottom properties. After an image has been successfully downloaded, it can be cached in-memory. This is useful for VirtualScroll by allowing image responses to be cached, and not rendered, until after scrolling has completed, which allows for smoother scrolling.

Sorry my comment above is not clear. You can set a class for modal by this way. Then you can style by that class. But if you want your modal fit the content if i understood correctlyit is impossible because modal is placed out side your page and does not have any relation with your page.
