designerspics.com is pretty basic, but it has everything you need!
femininestock.com – just one pack is out at the moment, but it looks like it’s full of the sort of white background, pretty stationery type photos that bloggers love at the moment!
foodiesfeed.com is focused on just food pictures – try to look through their archives without drooling!
pixabay.com is a searchable database of images – useful if you need something specific
stocksnap.io is another searchable site, but on this one you can also subscribe to their email updates about new images.
