Sharkcountry, I'm a serial offender. How do you resize a duplicate image to 600 px?

I use a Mac. I open the image in the preview program then use the resize image command under tools and type in 600 either in width for wide images or height for tall images. Preview will also let you crop and do simple color adjustments.
In windows, I used to use photoshop, but there's a couple of free programs that are a part of Windows. My PCs are running windows XP, so they are old. My photoshop is old too. I used Windows Paint before to do things.
I'm not familiar with windows vista or windows 10. This is right off of google.
Select the photos you want to resize, and then on the Edit tab, in the Properties group, click Resize.
Click the Select a size list, and then select a size for your photos. For a custom size, in the Maximum dimensions box, enter the maximum width you want your photos to be.
Click Resize and save.

This is a nice plus aboutApple/IPhone. If I have the pic in my Photo Album; I can post it. I've never tried to post a pic from another site, so I'm unsure about that. Generally I post pics I have taken myself or that have been forwarded to me and saved. My whole IPad and IPhone thing is all screwed now because I don't have a Cloud Account. Which means I have no pics on this IPad and have to go to one of my two IPhones to post with a pic. Don't ask me why I have two IPhones and two iPads and shit cell service. Long damn story. Lowel
