Can wedding photos be posted on the poster? Can I make a poster by taking the wedding photos back to the store?

Can a photo be as big as a poster? I think it's ok to stick it on the wall. Otherwise, how can people's wedding photos be enlarged and hung on the wall? Can I make a poster if I go to the photo studio to enlarge the print film of wedding photos and take it to the store? If the landlord has a negative film in his hand, it is no problem to make a poster. However, digital photography is widely used now, and the negatives are often CDs or USB flash drives. At this time, if you want to judge whether you can make a poster, you must confirm its resolution. The bigger the poster, the clearer it is. The smaller, the more blurred. Usually, merchants will not give customers the largest size manuscripts (for many reasons). If the time interval is not long, and there are still large-capacity manuscripts in the store, it may be better to do it at the shooting merchant's side (which is also one of the above reasons). The conclusion is ok, and it is recommended to send it to the original photographer. How to put a photo on a poster? Drag the photo directly to the poster in ps software, and then adjust the position and size.
