Many companies use this software for editing photos.

I use this for our company work and this works perfectly for image editing process.

We were in the 'stone age' before Ziflow - we were using email, dropbox and a project management platform to collect feedback on creative files/projects - it was a nightmare to manage. Ziflow helps streamline this process, and much more. Some features we love include... Ziflow accepts so many different creative file types (we haven't found any they don't accept). Workflows with automated stages make sure we have the right people reviewing at the right time. Security was important to our company, and Ziflow goes well beyond what the competitors offer. Customer support is great - if we ever have questions or problems they quickly respond and address.

I've tried other online proofing software but Ziflow is head and shoulders above the others. It's a bit more money than some of the other cheaper proofing solutions but you certainly get you money's worth with features and customer support.
