Step 3. Press "enter". Safari will open again and it will allow to load the local XML and Http files.

3. Chrome --- Error: NETWORK-ERR: XMLHttpRequest Exception 101

Because the default settings in Chrome disallow XML and Http file request, so you are unable to open your HTML5 slideshow in Chrome and Opera unless you change the default settings.

Step 1. Right click your Chrome shortcut, choose “Properties”, and find “Target”.

The exmaple of the original content in “Target” is "C:\Program Files\Google\Chrome\Application\chrome.exe", as shown in the following figure.

Step 2. Add " --allow-file-access-from-files" to the end of the content.

In the example above, the original content is "C:\ProgramFiles\Google\Chrome\Application\chrome.exe", you need to change it to "C:\ProgramFiles\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files.

Step 3. Save your change.
