Hard to say the exact reason, but it sounds like some problem with the picture metadata (extra data in the image file containing image details such as date, pixel size, camera model, exposure, and orientation). Over the years there have been a variety of formats for these attributes and apparently our software has had problems of reading whatever your graphics program had saved in the file.

Would you please state the details of your graphics program?

Can you not save the image in another (e,g, simpler) format?

That said, for the past couple of months I still am unable to upload more than one image at a time into Headlines and Groups. It's the only site where this is an issue, and I've tried IE, Firefox and Google Chrome. Previous to that there were no issues.

Apparently no one else here has reported the same problem.

Rob, this indeed sounds like an odd phenomenon. By design, iModeler supports uploading multiple files, but practical realisation of this feature relies on browser support. Upload of multiple files with a "Select files..." button is said to be supported in current versions of Chrome, Firefox, Internet Explorer, Safari and Opera.

A possible workaround is trying to drag-and-drop files from your computer directly into the image uploader on the post form.

Please let me know on occasion if this other method works or not.

I actually get the same problem with inverted images when I try uploading from my iPad. Curiously it's not an issue on my Mac, so I always resort to using the 'big computer' if I'm going to post stuff on iModeler. I have to upload photos from the iPad to the Mac in the first place and then re-export them as a low res JPEG prior to uploading them here. It's a work around for anyone who might be experiencing the same issues.
