I’ve been using Google’s PICASA Photo program for as long as it’s been around, to work with photos that I took. Last year, Google decided to discontinue it, with no further support. The software was still available online but no longer, at least that I can find.

I only have photos taken with my phone now, and don’t even own a regular camera .

Any suggestions on a simple-to-use PC program that a non-expert like me can use to cut and trim and possibly make minor corrections to color etc?

I use Gimp, it is open source but may be a bit more complex than you want, but it is really only about finding the cut, crop, rotate, scale and color tools.

It has been around for a long time and does not appear to be going away any time soon.

I have been using photoshop 7 for many years. IHMO it is easy to learn and easey to operate.It is available on the internet. I prefer it over some of the newer iteritation.

I second Bang's recommendation. If you want free or inexpensive, use the Gimp. It does about 80% of what Photoshop does for 0% of the price :)

Or sign up for Photoshop CC. I *hate* their monthly subscription model, but I've been using Photoshop (and Premiere, and After-Effects, and Acrobat, and so much more) that I basically bit the bullet and paid up. I pay $49 a month for the "full" CC subscription, but you can get just Photoshop and Bridge for $19 a month or less.
