What are Inline Graphics on a Web Page?

Google classifies "inline graphics" as image files. Inline graphics are images that are embedded directly into the HTML of a web page, rather than being linked to from an external source. They are typically identified by their extensions, such as .jpg, .png, and .gif. Google uses a variety of factors to identify and classify inline graphics, including their file extensions, their MIME types, and their content. For example, if an image has a .jpg extension and a MIME type of image/jpeg, Google will classify it as a JPEG image. Their classification of inline graphics is important for a number of reasons. First, it helps Google to deliver the most relevant and accurate search results. For example, if you search for "cats," Google will be able to show you images of cats that are embedded directly into web pages, not just images that are linked to from external sources.
Second, Google's classification of inline graphics helps to ensure that images are displayed correctly on all devices. For example, Google will be able to convert inline graphics to a different format if necessary, so that they can be displayed on devices that do not support the original format. Finally, Google's classification of inline graphics helps to protect users from harmful content. For example, Google can identify and remove inline graphics that contain malware or that are sexually explicit. Here are some examples of inline graphics:

1. An image of a cat that is embedded directly into a web page about cats
2. A logo that is embedded in the header of a website
3. A graph that is embedded in a blog post about a scientific study

Google's classification of inline graphics is an important part of its efforts to provide users with the best possible experience. Inline graphics are image files (or picture files) referred to within the text of a Web page and are identified by their extensions. Your browser can display them without using an external or helper application. The most common types of inline graphics (or picture files) are the GIF format and the JPEG format.

With so many image file formats available, BMP, EPS, JPEG, PNG, and GIF:
Question: How do you determine which is right for your email? Each format produces variances in file size, compression, and quality. To make things more confusing, support for specific file types can also vary between email clients. I will weigh the pros and cons of the JPEG file format.

JPEG images (short for Joint Photographic Experts Group) are full-color images that dedicate at least 24 bits of memory to each pixel, resulting in images that can incorporate 16.8 million colors, and are frequently referenced by their file extension, JPG. JPEGs are also lossy, meaning they retain all color information, but compress file size by selectively discarding data, and that compression can result in a loss of quality. In most design programs, you can choose the degree of compression you wish to apply to individual images, just be aware that by doing so, you also will alter the quality of the image. As a result, if you choose the maximum quality option, your image will most likely be indistinguishable from your original photograph, albeit with a correspondingly larger file size
