When viewed on the computer the shots are in portrait. So, tips are welcome. I don't like it myself and already asked how to get rid of this issue.

Not an expert on this but apparently JPG images can store the actual image data in any orientation, but then use some kind of orientation flag in the file that tells apps, including the browser, to render the file from left to right instead of top to bottom. Presumably they do this so photos can be taken with the camera sideways or even upside down, and the device (which can track which direction the camera is oriented when the pic is taken) doesn’t have to turn the data sideways while it’s being saved, and doesn’t have to re-encode the file when you hit the Rotate button in your photo viewer.

You can see this in action if you click on one of the sideways thumbnails and it takes a couple seconds to load up the whole image. Instead of filling in from top to bottom like most pics, it fills in from the left. So the browser knows about this and your device’s photo viewer knows about this, but the vBulletin thumbnail creator doesn’t know about this. It just treats the “top” lines in the file as the top of the image, because that’s the way it is stored maybe 90% of the time.

As I mentioned before, rotating the file in your photo viewer app, whether on a phone or a PC, usually doesn’t change anything but that orientation flag. When I’ve needed to force the actual image data to get re-encoded in the right order, I’ve used the very basic Paint app on Windows. But even this might be a pain for the non-techie: I think Paint detects the orientation flag, too, so it might open your images the right way up, and if you rotate it from there, it will end up rotated wrong.

I actually had to deal with this yesterday for a post on Women of Smugmug. I had to go into the Photo viewer and turn the image to the wrong direction (so that its orientation flag matched the actual direction the data was in) before I opened it up in Paint, hit the Rotate 90 degrees button, and saved it.

I know that’s a lot to read, but I hope it helps. Short version: try re-saving in Paint. If that doesn’t work, rotate it in your Photo app and then fix the rotation in Paint and save again. Then preview it on the forum after you upload it.

I don’t think it’s the most pressing problem with OCC’s software, but I hope they can get that fixed someday.
