I took a photo of my arduino hardware with my samsung S7 edge for a discussion thread.
I cropped and resampled it in Photoshop so it was only 194KB
But when I tried to upload the photo I get message that it failed security checks and to consult the administrator. WTF! I've been doing same method for years, what's happened here??
(see attached snippet)
I tried attaching same photo to this post, but same failure. So there's clearly something the uploader doesn't like about my photo.
I have occasionally had problems wth JPGs and then had no problem when I uploaded the same image as a PNG. I wonder if it may be something to do with background (non image) data in the file?
