You''ll be an expert very soon :O) 1st, what cam\phone\device, & regarding possible apps (programs) for image editing, preferred os: android, apple, win, chrome, linux ?
Most phones will (should) let you make a resized copy without the need of any outside app. If not, there are dozens of easy ways to downsize any image to a suitable size > numbers of pixels for good screen viewing \ file size for fast download speed.
F.ex. my Samsung phone got this in the stock Gallery app. Pick a size, then Save as copy if one wants to keep the original fullsize photo untouched.
