Not sure, what are you struggling with, but I'll try to help if I can. Resizing a picture is a simple task. Just set the longer side of the pic to 700px and keep it proportional. You might want to crop it before you resize it, if it's a long/wide image. It can be done with most photo editors, including PS5. When it comes to saving quality, I'm sure you can do it with PS5 too. When you done resizing your picture, hit 'Save as...', choose JPEG format and look for 'advanced' button somewhere. There should be an option to choose quality. AFAIR, 7 is a regular option, to keep good quality and maintain decent file size. Hope that helps
Oh, and also well done! for getting those great pictures without PS, I thought you were editing them Or perhaps you did, but somehow else? Idk much much about photography, but a bit about PS as I used to do some basic editing of so called 'digital art'
thank you a lot of them are unedited and the ones I did edit were using a picnic or picas just changing the brightness a biit im crap with photoshop lol still having trouble with this saving to a 7 or 8 thingy might do a course or something lol
