Sure that offer stands.
It is literally no work to me since i just rightclick your attached image in my mailclient and save to mounted webspace. So the file you send to photocomp at mosushi de will be available under same filename at https://mosushi.de/misc/photocomp/... after i discover the email.
Since i am busier than i ever wanted it is wise to still use the shrinky tmo upload for direct result and send the email to me same time so you can edit your post after i notify of the upload (maybe much) later.
Practicallity 100
Instantaneity 0, lol.

EDIT:
pentona would be
