Yes, those ones would work is just that I normally use 60 ml and 120 ml for the workshops. Plus, 50ml frosted bottles for toners. New directions is discontinuing them. They are looking for another supplier but I’m not holding my breath since it’s been almost a year since their fist announced. Thank you!
You'll need to upload them to a free image hosting service first—Imgur (http://imgur.com/) is great and doesn't require you to sign up for an account. Simply click " New Post" at the top of the page, drag your images into the window that pops up, and the images will automatically upload. From there you can hover the images and copy the URL that appears; simply paste that URL into your post on a new line and the image will appear automatically when you post!
