I have an issue. I just posted some quality scans in the Blank Blu-ray Media Tests sub-forum.
I always grab all my disc scan images as png.
I upload them with New Post / Go Advanced / Manage Attachments.
However, regardless of whether my files are (with correct suffix) in .GIF or .PNG or .JPG format, they always get converted into .JPG format once I upload them in the "Manage Attachment" window.
This results not only of increase in file size, but also severe loss of quality.
Case in point:
Original PNG (at an external site)
Exact same PNG file uploaded via Manage Attachment feature into a new post which auto-converts it into .JPG:
How can I avoid the auto-convert to jpeg feature of attachments?
I know I can upload to an external site and just embed those images, and bypass the problem, but those external sites are not reliable and they keep destroying the images...
