File attachment types

Hi Kirby,

If I take a raw screenshot, it's .jpg, and I can upload it here OK.

But if I use iOS Photos to crop it, it's still .jpg, but I get the error message when I try to upload it. At least, the error message seems to be worded incorrectly: it says "extension jpg expected but extension png given".
But the cropped photo does have an extension .jpg.

The checks for file extensions are handled in php, so it's hard for me to do much about it, because I don't have access to modify that configuration. Can you send me the cropped file so I can investigate further?

Happy to, except it won't let me upload it here.

You can email it to me.

My email address is my last name, followed by the first letter in my first name, at the domain for the University of Michigan (5-letter university identifier followed by three letter education extension).

OMG!

Sounds like mathlish.

The 5-letter ID takes a bit of digging...

Thanks for sending the attachment, EdLee. I tried uploading here, and it seems to work?

I used the "Upload attachment" feature, and then used "Place inline". Are you using a different process?

Hi Kirby, same process but on an iphone5, Safari.

Using iPhone SE this time.

I'll try harder to see if I can find a way to reproduce this behavior..

I do notice that, on iPhome SE, just taking the screenshot gives me the file with png extension, but if I use the tool to crop, I get jpeg extension.

Seems I can upload both though

Currently on iOS 11.4 - maybe that's more important than the phone model.

iOS 10.x

Is it possible to upload animated GIFs here? I've got a 20-frame animation I want to share, size 4.1Mb. When I try to upload the file it looks as though it's working OK, but after about 30 seconds I get an error message saying "The image file you tried to attach is invalid." Have I hit a size limit (and if so, what exactly is the limit?), or is it a different problem?
