Hello and welcome (back).

I see from your
other post that you've found a way to download some pics. But the short answer is: save your pics onto somewhere where you know how to find them (eg a computer). Click on "post a reply", then click on "Upload image" below the text box. Then find your image and select your image file.
We do ask that you try to crop pictures as much as possible before downloading them; the easiest way to do this is just after you've taken the picture, use your phone or camera's "crop image" feature before saving it.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
