customer image editor integrated with custom photo printing site

I currently run a small business printing custom shower curtains ([login to view URL]). I'm presently using woocommerce with gravity forms to get the information I need from my customers. I recently came across [login to view URL] and I much prefer their image upload process. What I am looking for is a solution in which customers can upload and view their images on a product template, and do basic editing such as changing to black and white, zooming, flipping and rotating, and selecting a background color if the image doesn't fill the template. I'd also like it to warn customers if their image is lower resolution than the suggested image size. Ideally this would be integrated with wordpress and the site that I already have, but I'm not sure if this is possible so let me know, as I would be open to a different CMS if it was necessary. I found a PLR software I can buy for $200 called pixenate ([login to view URL]) and I'm not sure if it could be integrated into gravity forms and woocommerce that I already have designed, but I'd be willing to buy it if it would bring down the cost of my project. I also will likely expand outside of shower curtains in the near future, so I'd like to be able to change the size and look of the product template. In summary I basically want my site to function EXACTLY like [login to view URL] Please let me know how you intend on completing the project eg. integrating existing software into my site or custom coding new software etc.
