Yes -- I used that button to test for posting pics. But the allowed photo sizes posted from a computer, are really small. And that's okay if you need to save drive space and not result in having to scroll right and left because someone posted a huge photo.
But I was posting an image from the early 2000s which would be about 2.2 mb, relatively small -- and it is way too large for the website, so I had to move the photo into -- in my case Paperport, and crop most of the photo, copy it to another file in paperport and then post the cropped photo.
I participate occasionally on a gardening forum, and you can post your photos, and if you have a 16 mb photo, their software reduces it to about 640 x 400 size, or whatever size they accept -- no matter what size your original was -- it gets reduced to the size the forum can handle, automatically. It didn't use to do that 15 years ago -- at that time I would have to figure a way out to reduce the size of the photo posted, which I could do in Photobucket, but that meant uploading it to a separate site, and messing around with the size, and saving it, and then uploading it to the gardening site -- the new way is lickety split. By the way the site is
www.gardenweb.com if that helps to visualize and example, and they have 100 or so gardening forums.
