I've been using the debug function of W3 Total Cache to see what queries are sent to the database when pages are loaded in the browser. I saw this one in the list:
SELECT option_value FROM wp_options WHERE option_name = 'wp_smushit_gif_to_png' LIMIT 1
I'm not sure what this means, but it seems very odd that this is being sent to the database every single time a page from my site loads. I would think this plugin would only send queries to the database when you're uploading images.
Anyone know what's up with this?
