How do you watermark your photos when you post them online?
AYes. I won't post photos anymore without doing so. Edited: sorry, I didn't read that right. I use picassa. It's free, and you can watermark a bunch at a time.
Is Picassa a phone app only, or can you put it on a computer?
AI use it on my computer. I do not know if it's available in an app.
AThere are a lot of watermarking programs available. Google photo watermarking software, and a big list comes up. I chose Picassa because it worked with my existing software and is easy to edit/watermark. I'm not super bright when it comes to computers.
pixlr express is also an online editor that allows you to add a watermark. (option/alt + g is the © sign)
You can just use paint to add one, if you have nothing else.
