What is MIME type "image/x-ani-st"?
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
image/x-ani-st is a MIME type for files that contain Ani ST Script data. These files hold instructions to create or control animated images. They are processed by software that can interpret animated scripts.
- Main use: Running animation sequences that render visual movements.
- Other uses: Integrating custom animations in multimedia applications and specialized graphics programs.
- Key fact: It is a vendor-specific type; not every platform supports it by default.
- Technical point: The file contains both scripting code and animation data rather than a static image.
This MIME type is applied to files like SCR and STR. They are treated as animated image scripts rather than basic pictures.
For more detailed technical information on MIME types and animation scripts, you can check resources like IANA and software documentation sites.

FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type
on the command line. Many programming languages also provide libraries to detect MIME types.
Why are multiple MIME types listed for one extension?
Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
