i have installed the component on my local Server and importet a csv file which is possible within 30 sec limitation (about 200 books)
In yours local server you can set any time not only 30 sec. Please go to php.ini and check all variables with word "time". Also please check php function "set_time_limit"
after refetching amazon information pics are shown but no description and review is available.
CSV - import not support review recover. Description - for books - if it exist in book before export - it must recover.
also db connection to amazon is limited to 30 seconds using the AWS code given through your installation.
creating a new aws key in germany is impossible without paying to amazon.
Sorry, not full understand what you means. After import or manual books add - you can refetch info for all books what you wish. If you have some limitation with execute time - you may refetch info for 20 books per every times
