Okay, I have a huge group of photos that have an extremely large size resolution. Like 3515 x 2490 and its like 5 megabyte a picture. Is there a way i can take all the photos(about 30) and downsize them all at once?
Most image editors like PS have a batch execution for repetitive tasks like image resizing. In PS it's File > Automate > Batch... You have to record a set of actions first in the "Action" window tab.
