When I open my photos, I right click on the photo I want to upload to bring up my options, and then left click on "Properties." That will give you the file size, and it needs to be below 128 KB's. If it is more than that, resize the photo by reducing the pixels. About 550 X 375 or so should do it. You can see the exact file sizes on the photos below just underneath them. Once you save the reduced size, you should be able to post the photo, but it takes time to upload - it will not be instantaneous. And only one at a time. Don't try to upload two or more simultaneously, instead go back and modify once the first photo is showing. Anyway, that is what works from my desktop. I don't use a portable device. BTW, I am using these two bantam roosters in my breeding pens this year.
