I use software to make and resize gifs.
It’s called Animation Shop and is sold by Corel now (was JASC).
I googled “resize gif” online and found a bunch of resize sites.
Thanks Lady Jag. I have to keep looking on line till I find just the right one. It’s nice I can do some of them. I need to buy a good but easy software. Would love to try to create some gifs.
