I choose an image. For the text, I go to www.cooltext.com, find a font I like, and create the text with a transparent background. 140 point or higher is usually how large it needs to be.
I download the text image to my PC and then head to https://pixlr.com/editor, where I load the graphic image and then open a new layer and select the text image that goes over top the graphic image. I’m still not the best at moving it around; it’s a work in progress. I save the combined image to my PC and then upload it to the web site for use.
