We have recently added a Quick Photo Editor in our Photo submission portal for authors to quickly enhance their stock photos with some default effects and frames, but most importantly watermarking their image is kept optional for authors if they want to protect their rights and re-use of stock photos.
Here is the Quick Video on using Photo Editor and downloading edited images.
The Editor is kept with simple effects since the stock media is used for commercial purpose so authors and photographers uses professional photo editors which they are use to enhance photos and images but this editor is added for those authors who are bit less experienced are starting fresh in photography or have interest in it.
It could also be helpful for professionals for some extent, the objective is to promote the concept of stock media submissions because it is just a single click out of thousands of other clicks which make a difference and we never know which click that might be.
So go ahead and start submitting your photos which you think can be used commercially.
