At the moment are using a website based on TikiWiki 6.* LTS. Our web host has upgraded the PHP version to 5.4.25. This seems to cause problems with the display of images. The following are some of the error messages:
PHP Strict Standards: Non-static method Image::is_supported() should not be called statically in .../tiki-download_file.php on line 262
PHP Strict Standards: Only variables should be assigned by reference in .../tiki-download_file.php on line 332
Although we wish to upgrade in the future to TikiWiki 9.* LTS we'd hope to do this when ready. Is there anything that can be done to TikiWiki 6.* to make it co-exist with PHP 5.4.25.
