I don't know if you can send them from your cell phone but what I do is send them to my gmail from my phone and then open the email on my computer so I can tweak them if necessary plus resize them to fit on this website. I have Windows 11 on my computer and I just right click the photo and go down and click on "photos", open it up and click on "edit" at the top left corner. Do whatever is needed, save it under a new name, then go back to the screen and click on the 3 dots farther to the right at the top. This will give you the choice to resize the photo. Then save it again. It will come up saying its already there so I just click save or yes, whatever comes up and the photo is done. It may be a bit more work but at least I know I have it tweaked and resized ready to send to others if I so choose.
