Hello
chris B,
I am looking into this issue, but I think that the software believes it may be a corrupt image file. I have tested upload of images and all of them have worked for me. I believe that if the image is converted from the raw file into a .jpg image in the camera itself, it makes the forum software believe it is a potential malicious code masked as a .jpg and does not upload it.
If you open up your files in an image editor, and then save them locally, it should work without a problem. This is what I have gathered so far, but I am still looking into this issue.
- Hope this helps :)
Thanks.
