Take it into a program like gimp, paint, sai and turn it the correct way. Save it as an extension FA allows like png, jpeg and the like.. then post it.

Or give it to me and I'll do it and send it back.

I've had the same issue and I've found it happens more or less often on certain browsers. Sometimes closing the page and retrying works.

I noticed that! Thanks for the advice everyone

It has to do with the meta data in the photo's original orientation data. Some cameras write the image actually sideways and mark it with orientation, while others detect the orientation and write the image right side up directly to the card. Many image editing programs can read the data and auto-correct the image... but web browsers cannot. So you might look at it at home on your pc and it's right, and then on FA it's sideways.

The easiest way to fix this is to open the image in a simple paint program like MS Paint or something, and save the image over itself... that will write the image correctly and not rely on the camera's data.

Try some tests with your own programs... open the image with your browser on your PC and see what it looks like.
