Busy making lots of bots! Really enjoying it

Question about photos. I have done a form which can upload photos, the bot interacts with the photo and that works absolutely fine.

I have now created a new pickaxe which is a chat and enabled upload, in testing when I click on the upload button, we have access to text PDF + no image formats are available to upload. I tried uploading a JPEG and nothing happened.

So is it impossible to upload photos into a chat?

We have to use a form for photos.... or is this an incorrect assummation?
