I'm new to Photoshop. Just downloaded the trial version last night. What I'm trying to do is edit a PNG file. I was able to edit the file, but after saving it I noticed that all the metadata (e.g. Date/Time, etc.) was overwritten. Most of that information I don't really care about, but Date/Time I would really like to keep. Is there a way to get it to preserve the original information?

Thanks,
Nick
