Marius are dreptare.
Dar...daca folosesti elemente din imagini modificate, nu e o problema. Mai ales daca noua imagine nu e in raport mare, identica cu originalul.
Poti folosi elemente din imagini, cu care sa realizezi o alta imagine, proprie si diferita.
ps: as dori sa imi confirme sau sa imi infirme cineva faptul ca, daca schimbi o imagine preluata mai mult de 75%, ea poate fi folosita. Eu cel putin asa auzisem.
ROYALTY FREE - A term often used in photography CD collections or on CD collections of images. May also refer to the purchase of images from online sources.

An initial fee is paid for the purchase of the CD, online images or a collection of photos, and the purchaser may use the image(s) as often as required within the license terms and conditions without paying for the use of the image each time the image is used.

Please note that the purchase of a CD collection does not offer unlimited or unrestricted use of the images contained on the CD. Most distributors have very specific limitations on how the images can be used, placed online electronically, or reprinted.

Always read the licensing terms and conditions for each distributor.
