Hello, I can create your project for OSX in python, it would be easy for you to use the program in another operating system.
I think it's the best way to do it, I can make the application allow you to select the images you want once you've pasted the link, you could also select the text you want for the description as well as the price, all once the application has extracted the correct data from the link you have selected.
I hope to work with you on this project, have a good day.
