Interactive elements in online content often lead to substantially increased total payload size to be delivered to a client device, e.g., to render a page. Delivering such content may introduce latency, thus degrading user experience. The techniques of this disclosure address this issue by delivering a compressed static image that mimics the visual feel of interactive elements of content. The image can be delivered faster because its size is significantly smaller than that of the interactive content. Subsequently, the image is replaced with the corresponding interactive content. With user consent, the replacement of the image with the corresponding content may be based on user interaction with a page on which the content is placed.
