Instead of performing a "checkout", you need to perform an "export". Is this action available with TortoiseSVN?

"Export" is available in tortoise ;-)

I have added a feature in the extension manager, now you can directly request for a Subversion hosting on piwigo.org :-)

Once you have created your extension, click on the "Request Subversion Hosting" button. piwigo.org administrators will receive an email with instructions to create your extension in the repository.
