Whats the maximum amount of copies allowed?
The total number of copies in which you include the image should not exceed 500,000 copies for the Royalty Free license. This doesn’t apply for electronic use. If you exceed this number, you will have to acquire the I-EL (increase maximum copies) extended license which allows you to print up to 2,500,000 copies. If you exceed this amount too, you will have to acquire a new I-EL license for more 2,500,000 copies. These amounts and the I-EL license applies only to the regular Royalty Free license. For usage types as the ones from the W-EL license or P-EL license you will have to acquire that specific license once again in order to double the allowed number of copies.
