File attachment types

I just tried to attach a .pdf file.

The board blocked it with "The extension pdf is not allowed."

Is this intentional? What file extensions are allowed?

Go ahead and try it now...

100% sure it works now.

Same problem here, but with .csv and .txt extensions. Can you clarify whether it's by design or a bug?

Not a bug, per se. it's just that there is a whitelist if allowed extensions for uploading. We disallow filed with arbitrary extension types to be uploaded. I don't see harm in csv or txt, so I've whitelisted them.

Is .png disallowed for images ?

Ugh, yes. On iOS, a default screenshot is saved as a .jpg.
But iOS's Photos app's Crop function saves it as .png, which is disallowed for image upload here... :-?

Is there a problem with allowing .png attachment here ?

I haven't had a problem uploading png files. I've posted a few images on my journal in this format.

Hi BlindGroup,

Thanks. Were you using iOS Photos to crop a jpg photo, which became a png on your iOS device -- and you were able to upload it here ?

Kirby · Post by **Kirby** » Wed Sep 19, 2018 4:04 pm

gif, jpeg, jpg, png, tga, tif, and tiff are the currently allowed image types

They were crops of screen shots in Windows saved as png.

Ed, are you talking about the case of using image tags rather than just "attaching" a png file?

Hi Dave, Kirby,

1. iOS Photos app: Crop a screenshot, save it to iOS "Photo Library"
2. L19 > Post Reply > Filename > tap "Choose File" button
3. iOS > iphone "Photo Library" > pick cropped photo from (1)
4. tap "Add the file"
5. Error message: Image file type mismatch: expected extension jpg but extension png given

What's the filename extension?

Hi Tryss,

It's iOS; files and filenames are not readily shown.
Please see the reproducible steps and error message in post 13.

The error message, raw, uncropped screenshot in post 13 was .PNG.

The iOS Photos cropped photo has an unknown extension, since L19 refuses to upload it ( please see step 5, post 13, of the error message ).

This one off the net is .JPG:

Life In 19x19
