Images uploaded from cameras can have predictable (and guessable) filenames. Prevent predictable filenames. Use Unpreditable Image Filenames.

Christopher Finke

<p>Most cameras and smartphones number their images in a predictable format. For example, iPhones use the format <code>IMG_0001.jpg</code>, <code>IMG_0002.jpg</code>, etc. If you upload <code>IMG_0345.jpg</code> to a post and publish it and then upload <code>IMG_0346.jpg</code> to a post that you are not yet ready to publish, someone could guess the URL of <code>IMG_0346.jpg</code> and see it before you’re ready.</p>
<p>The Unpredictable Image Filenames plugin renames image files when you upload them to a sufficiently unguessable name. For example, <code>IMG_0345.jpg</code> could be renamed <code>334AB1E8-28AB-4BE1-882D-3C112E95F055.jpg</code>, and <code>IMG_0346.jpg</code> could be renamed <code>A67C9CF9-0BB5-4FB4-AD03-DCB294F853EC.jpg</code>. Try and guess that!</p>
