Question

On an HTML page, using the INPUT tag, how can you get it so that when you click the browse button that it filters for image files only? Bonus points if it can include .bmp files.

Answer 1

With the accept attribute, you list the mime types to accept.

<form action="form_action.asp" accept="image/gif, image/jpeg">
    First name: <input type="text" name="fname" /><br />
    Last name: <input type="text" name="lname" /><br />
    Your image: <input type="file" name="pic" id="pic" /><br />
    <input type="submit" value="Submit" />
</form>
