Pixo - Image editor for your web app
If your users deal with images (photos, product images, etc.) it will be great if they have the ability to apply some basic editing after upload, e.g. adjust brightness and contrast for sharper view, crop, add some text, etc. However, if image editing is not the primary feature of your product, the profit from investment in such secondary feature won't cover the costs. Integrating a 3rd party image editor appears to be a wiser choice.
