When the aspect ratio of the provided size does not match the image aspect ratio, the image is scaled and centered with respect to the size in order to maintain aspect ratio. The provided transform is applied after this operation. The PageElementProperties.size property is optional. If you don't specify the size, the default size of the image is used.

The length of the ID must not be less than 5 or greater than 50. If you don't specify an ID, a unique one is generated.
-  *   `url` (*type:* `String.t`, *default:* `nil`) - The image URL. The image is fetched once at insertion time and a copy is stored for display inside the presentation. Images must be less than 50MB in size, cannot exceed 25 megapixels, and must be in one of PNG, JPEG, or GIF format. The provided URL can be at most 2 kB in length. The URL itself is saved with the image, and exposed via the Image.source_url field.
