Working with Media - The Images Directory

Yes, by adding the relevant file format extension to the highlighted fields shown in the images above:

• Allowed Extensions, and
• Legal MIME Types.

But we strongly advise that you consider the potential impact on your website's security of making such changes.

If you are using a version of Joomla! CMS which pre-dates Joomla 4.1 then you should ensure that the upload of Flash files is blocked.

Check and remove (if present) the following references to swf files from the Legal Extensions field:

• swf,
• SWF.

Check and remove (if present) the following reference to x-shockwave-flash files from the Legal MIME Types field:

• application/x-shockwave-flash.

The default value in the Maximum Size field (highlighted in the image above) is 10 MB.

If this is too small for your needs then you can change the value.

The absolute maximum file size that you may upload is however set by your hosting provider.

It is called the Server Upload Limit.

If your website is using the JCE Content Editor, follow these steps to see what the Server Upload Limit is:

1. select JCE Content Editor from the Components menu in the sidebar of your website's Dashboard;
2. select Editor Profiles;
3. select Editor Parameters;
4. scroll down until you see Upload File Size (KB) shown in the image below.

The Server Upload Limit set by your hosting provider will be displayed in very small text on the right (in landscape view).

If it is too low then contact your hosting provider to request an increase in the limit.

You could alternatively upload large files to the server using File Transfer Protocol (FTP).

Note: the Upload file size (KB) figure shown in the above image does not limit the size of files that can be uploaded via the Media screen.

The figure limits the size of file that can be uploaded using the JCE Content Editor when editing website content.

Again, you can increase its value.

If you try to upload a Media file type via the Media Manager and the file type is not supported then you will see the following message.

The default Joomla! CMS Media Options do not permit the following Microsoft file formats to be uploaded:

• .DOC and
• .DOCX

You could amend the Media Options settings to permit such file types to be uploaded.

A better strategy would be to in future export your DOC files to PDF.

PDF file uploads are by default permitted.

PDF files can be previewed in a a web browser without having to be first downloaded by the reader.
