I tried to upload an image of 1894 x 19060 (Firefox screenshot). I keep having the error saying this is not an image. I tried jpeg, png. Tried reducing the jpeg to less than 1MB.
Any idea why is that ?
Is There Any Image Dimension/Size Restriction for Uploading to "Files" ?

, 'Tried reducing the jpeg to less than 1MB.' but you don't indicate if that solved the problem, and if so, how you reduced the file size (cropping, resolution etc).
I mean none of that solve the problem.To reduce the jpeg size I reduce the quality down to like 40%.
The way I solved it was to crop the image into 2 images thus wondering about image dimension limit.
The original image was this one : https://i.imgur.com/RlpW6uO.png
Anyway to move this post to that forum ?
I would leave your post here and just link to it in the moderator forum.
That forum is private between you and them. That way you can find out the answer and then come back here to let everyone else know.
They may well answer your question here but in case they don’t see it going directly will ensure they do.
I’m sure others would be curious too.
Current restriction of uploaded files
- Maximum size: 10MB
- Extensions allowed: GIF, JPEG, JPG, PNG, PDF
If images are larger than 4096x4096 it would be resized down. What exact error message are you getting?

File upload error : Not an image file
You can try to download the image from here: https://i.imgur.com/RlpW6uO.png
and upload it yourself. Hopefully that is reproducible.It appears that the backend we use (ImageMagick) does not recognise it as a proper image file. I suspect that ImageMagick we use does support height over 16k pixels.
so 16k dimension image is a limitation then. Good to know. Probably not often encounter :-p
How big was the original file? The resolution is one factor, but there are others, not least the colour / greyscale / black and white settings, but also compression for a lossy format like jpeg.
You also say that you, 'Tried reducing the jpeg to less than 1MB.' but you don't indicate if that solved the problem, and if so, how you reduced the file size (cropping, resolution etc).
Maybe upload the file to another fileshare (Google Drive or whatever) and link to it here so that we can see.
