Can anyone recommend a free photo editor for Windows 8 please?
Preferably not the online ones.

Just something to do very basic touch-ups (Gimp is too advanced).

Thanks!

Paint.net

Pixlr, either the download version or the online. Both are pretty good.

+1 for Pixlr.

Check out Lightzone:

+1 for Paint.net
Been using it for several years.
10/10 from me

If you have an Adobe account, Adobe CS2.

Thanks all! Will give them all a go.

Picasa

PhotoPad Image Editor (free version)

Paint.net is my usual editor, occassionaly Picasa. Might check out the others mentioned to see if I’m missing anything.

I’ve now tried Paint.net & Pixlr.

Preferring Pixlr because it has a straighten tool but mostly because it has a tablet mode which makes accessing the adjustments tools a little bit slicker.

Thanks again for the suggestions 🙂

irfanview always used to be good

If you want to “edit photos” with a Photoshop-a-like art package to actually touch up bits and change stuff around, Gimp is popular but I prefer Paint.Net (because it reminds me a lot of the old Paint Shop Pro). If by “edit” you mean the sort of things you’d get in-camera like white balance and exposure, then something like Picasa might be more appropriate.
