Usually I add text to graphics like this one on a program on my machine. But someone asked how to put graphics on a picture, and she owns a Mac. (For reasons to do with inheriting machines free from my husband, I tend to use PCs).
So the hunt was on for a platform-independent solution.
Which led me to www.pixlr.com.
And then to my first ever (probably hilariously bad) attempt at describing a process via screen capture. (Eg, next time, I'll minimize that Huuuuge Google ad on the screen...)
Have a laugh, anyway...
