To restrict the <input type="file"> element to accept only image files, you can set the accept attribute to specify the MIME types that are accepted. The accept attribute can specify one or more MIME types separated by commas.
For example, if you want to allow users to upload only image files, you can set the accept attribute to accept common image file formats, as shown below:
<input type="file" accept="image/png, image/jpeg, image/gif">
In this example, the accept attribute specifies three image formats:
image/png- PNG formatimage/jpeg- JPEG formatimage/gif- GIF format
When the user clicks this input field to select a file, the file dialog will filter and only display these specific image file types, making it easier for users to select the correct file type and minimizing the risk of accidentally uploading non-image files.
You can also use the wildcard image/* to allow all types of image files:
<input type="file" accept="image/*">
This setup allows users to upload any image file format without being limited to specific types. While this may be more convenient, if you want to ensure only specific image formats are accepted, the previous method is more appropriate and strict.
