I’m afraid that with Firefox i can perfectly click on your photos and save them to my desktop, of course i haven’t done that but that browser seems to allow it.

The theme i am using ( Suffusion ) already has many built in optimization options and with the addition of something like W3 Total Cache i don’t think i need the plugin you discuss.

I do hope plugin authors continue to update their plugins though, i am using one called Simply Exclude which hasn’t been updated for a long time but still works, no idea if it will fail one day though thus it would be nice if such plugins were kept up to date.
