Specify that the server accepts only gif and jpeg files in the file upload:
The <form> accept attribute is not supported in HTML5.
The accept attribute specifies the types of files that the server accepts (that can be submitted through a file upload).
Tip: Look at the <input> accept attribute instead.
Tip: Do NOT use this attribute as a validation tool. File uploads should be validated on the server.
