Can you change the resolution of a photo with photoshop? I'm trying to make a woven blanket as a gift and it keeps telling me the resolution of my photos are too low. It suggests the resolution should be 2000x3000.
Yes, you can use Photoshop to change the size and resolution of an image -- Image > Image Size. That said, if you take a small image and just blow it up, the resulting picture will be very blocky and pixelated. I'm not sure what you're trying to do, but you should definitely keep this limitation in mind.
