PHP error message when making gallery

my gallery is up, plugin configured, images in folder, and the right permissions set, and I get this message when trying to access the gallery page:
PHP Error Message

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 9572 bytes) in /home/a2791231/public_html/joomla/plugins/content/photogallery.php on line 59

This is the second gallery plugin I have tried to install, and had the same error message the first time (the gallery was YOOgallery)

Can you help with this please?
Thanks in advance.
Yours,
Stephen

I believe it's shared hosting. In this case, you can't fix the error yourself. Please contact your hosting support and ask them to increase allowed memory size in php.ini file.
