Title Link Addition declined for many images I submitted

Hello! I recently submitted more than 20 images (mainly posters) for different movies/TV shows in Croatian. A small number of them got accepted entirely, but the majority did not. Their Title Link Addition was declined with the reason being that they do "not meet contribution guidelines." The images in question all come from official sources (either websites of local cinemas or the streaming platform HBO Max). Here is a list of the contributions I am referring to: #230612-190648-054702 #230612-180035-492902 #230612-175915-840602 #230612-175812-623902 #230612-175614-689102 #230612-175435-861602 #230612-175237-921902 #230612-174831-870502 #230612-174440-611202 #230612-174303-682802 #230612-174134-168302 #230612-173945-452002 #230612-173726-347202 #230612-173327-138102 #230612-173016-412202 #230612-171637-053502 #230612-171439-170202 #230612-170806-937302 #230612-170553-167302 #230612-165930-190602 #230612-165333-309502 #230612-165049-509402 #230610-115231-095302 If someone could explain what precisely the issue is with these images, that would be very helpful. Also, it has happened once before that an image I submitted was declined in the Title Link Addition part even though everything was in order. Can I do something to help prevent such accidental rejections? Thank you very much and best regards!
