; Image uploader for HexDroid
;
; /img picks an image and uploads it, then sends the URL to the channel.
; /imgme does the same but shows the URL only to you.
;
; Written for the Paste Image Uploader PHP endpoint, which:
; - reads the file from the form field "images"
; - strips EXIF when the form field "strip_exif" is set
; - answers 200 with {"results":[{"success":true,"filePath":"/img/img_x.png",...}]}
; or {"results":[{"success":false,"error":"..."}]}
; - returns a site-absolute path, not a full URL, so %img_base supplies the origin
;
; SETTINGS
; %img_ep exact upload URL including the file name. A directory URL answers 301 and
; the upload is not redirected, on purpose: a redirect to another host would
; send your file somewhere HexDroid never checked.
; %img_base scheme and host the returned path hangs off, no trailing slash.
; %img_field form field the server reads the file from.
; %img_auth optional, a whole header line, e.g. Authorization: Bearer abc123
;
; The picker never opens on its own: HexDroid asks first, and you choose the file. The
; script is handed a token for that one file, not a path, and can read nothing else.
