Thank you for the information, it is very kind of you @johnnyray These days I am very busy but I will keep on mind to check about Amazon... For me the proble was not to make a great cover because as I like photogray, as you know, I wanted to use some of them for the cover of my books, the problem was to upload them to Bubok, where I publish my books... Now, I understand you can upload any photograph/cover you wish to Amazon, which is great... I keep that link for the future, just in case. Best.
