Pictures upload failing when creating a new observation via web browser

Is anyone still experiencing the problem described in the first post? If so, it would be helpful to get more information like:

  • What operating system are you using, and what version?
  • What web browser are you using and what version?

If there are any updates to your OS or browser I’d recommend applying them and trying again. If you are still having the problem and are willing to spend some time working with me to investigate it, please direct message me.

This is out of scope of this bug report, but I’d recommend never uploading more than about 50 photos at one time. We’ve considered adding a hard limit, but haven’t done that yet.

I previously reported this issue but I was able to upload as usual from this machine/browser/OS so it looks like it’s been fixed for me, thank you

@pleary @tiwane Ugh I spoke too soon :(

The issue occurs in all browsers (Chrome, Safari, Firefox) on Mac OS 12.5.1. I reproduced it on another laptop running 12.5. My connectivity seems to be working fine otherwise, I have (up) 200.49 Mbps / (down) 33.20 Mbps via a wireless router, no firewall / proxy / port restriction configured on my network, and I am able to download and upload photos on other websites just fine (including the screenshot above).

@pleary DM’ing you.

I wrote an email on Sep 8 reporting this error and Tony Iwane directed me to this forum post, unfortunately I’ve been caught up with university stuff (just started) and haven’t been able to leave a reply or explain my case in detail. I’m on Windows 10 Home and I use Firefox, which I think is updated. I also tried in Chrome and got the same error.
I experienced it with multiple pictures last time I uploaded, the next day I uploaded the files to a blank observation that I had made, and it worked as usual.
Today I was uploading and this time it only happened with 3 files; 2 out of those 3 have a warning when opened on the Photos app of my PC, it reads; “Sorry, Photos can’t open this file because the format is currently unsupported, or the file is corrupted.” I’m not sure why I’m getting this, but the first time I experienced the iNaturalist error I don’t recall getting such a warning on the Photos app.

I tried to reupload the file that isn’t corrupted and it worked as usual.


This image took 57 attempts before it suddenly “worked”. I also tried cloning the same photo 100 times and dragging them all in. On average, 6/100 worked and the others were “insta-rejected” by the site.

It must be some weird connection thing. Is there a very short window for a lost connection to “time out” and just give up? As far as I know my connection is not bad at all and I’ve never had any interruption issues elsewhere, but I don’t see how else this could happen. The fact there is no real trend and it’s seemingly random must correlate to some amount of site use x internet connection of the PC.

Seems to be the same problem as my post here:

I’m having the same issue as jmartin54. Using a MacBook Pro and Safari. Haven’t been able to upload images since the server issues at iNaturalist. Just attempted to upload 12 images. All twelve appeared as expected on the page; all but two “disappeared” from the page.

are the files that you’re uploading coming directly from your computer? or are they coming from device connected by USB? or are they coming off of a cloud storage service? if cloud, which one? (it looks like you might be using 2 different ones.)

does it make a difference if you select the files from the file selector rather than dragging and dropping them into the browser window?

It makes no difference whether I drag the files from an alternative storage (USB, cloud, dropbox) or natively from file explorer on my computer. I have tried various methods.
