Some tips to make your submissions in FA look better
11 years ago
If you're posting a PNG that's bigger than 1280 pixels wide or high, FA will generate a scaled down JPEG of it, unlike deviantART & Weasyl which generate PNGs for thumbnails and previews. Here are a pair of tips:
1) Before posting, reduce your image's size to 1280x1280 or lower.
2) In your submission's page, click on Change submission file, and choose the same PNG file you wanted to upload. This will bypass FA's image resolution detector, though I'm not sure if the admins still disapproves or not of anything wider than 1280 pixels in this site.
If the size thing mentioned above isn't the problem and you still see your submission's quality or transparency "destroyed by FA", then it's likely you aren't seeing it in Full View.

I just did that last night without realizing it was a loop hole in the system.
