There were some compatibility issues between our Simple Image Menu Joomla module and PHP 5.3 so we had to do some minor changes to the code. The rest of the module is intact. If your server is moving to a newer version of PHP then make sure you are running the new version (1.0.1) in order to avoid any issues.
Please inform us if you spot any changes in behaviour compared to the previous version so that we can correct any errors.
As usual the module can be downloaded from here.
