What do you recommend for changing image orientation or rotating an image by 90 degrees?

I have an application where I am importing images into a 5.1.12 version of TiddlyWiki.  But all of the images come in in landscape mode and some should in portrait or vertical mode and I haven't been able to figure out how to rotate them.

I use ImageMagick for my image manipulations.

The Convert command will do it for you. See http://www.imagemagick.org/script/command-line-options.php#rotate

Oh ok, I was thinking there was a way to do it in TiddlyWiki for some reason.  But I can certainly rotate the image with an image editor first.

The issue here sounds like the problem that some cameras encode portrait images as landscape bitmaps along with a metadata command to rotate the image by 90 degrees on rendering. Unfortunately, some browsers don't understand the "rotate 90 degrees" command. Generally, it has to be fixed by opening and resaving the image in an image editor.

Best wishes

Yes, that was the case, and resaving solved the problem.
