Are you taking pictures with your phone or with a dedicated camera? And are you using a windows computer or a Mac?
I can't help you if you are using a Mac.
An Android phone is most likely already hooked up to your Google account and can be set to automatically upload your picture to Google Photos.
Through Google photos you can easily edit pictures within Google Photos, download them to your computer and then upload them to whatever site you want.
It is a little more complicated if you are using an actual camera! But you would download from your camera to your computer and then you can upload to Google Photos, edit the picture, download to your computer and them upload where ever you want. (that is essentially using Google Photos as your photo editing software - it is free with quite a bit of storage, but if you have a lot of photos uploaded you may need to purchase additional space - about $20 a year)
