PS. posting here is the right thing to do. PMs to volunteer moderators will not be appreciated.
If that is the case, then they should not have the website display the message "...Please consult the forum administrator".
For any feedback or reporting an issue with the website please email webmaster (at) arduino.cc
The "Attach" section of a new post should not just have the, "Allowed file types: doc, gif, jpg, mpg, pdf, png, txt, zip, c, h, cpp, ino, pde. Restrictions: maximum total size 1 MB, maximum individual size 1 MB", but should also add that no files can have Exif data embedded. It had me stumped as most would be.
but should also add that no files can have Exif data embedded.
I suspect it may be because the JPG has Exif data.
