I guess it didn't have anything to do with my Pro-account expiring, but I still don't know what exactly caused it. In my very first mail I mentioned I have no problem uploading things, so they replied that they tested uploading and it worked for them. huh? I replied again saying the issue wasn't uploading, because the pictures were already uploaded and looking fine until they suddenly had a drop in quality.
Their final conclusion:
We are fairly certain, that there may have been a technical issue at the time
of upload which caused the reduction in filesize, and that perhaps, you did
not notice this at the time of upload.
...right. 'Cause I do not see the difference between a pixellated blob and a head.
Anyway, it would really suck if this was actually true, because that would mean none of you could've ever saved the hq-versions of my icons. And I need those!
I've re-uploaded my last three icon post (except for an icon or two I don't have anymore), but those are the only posts I still have the icons of. So, if you've saved some of my icons and you could send them my way, I would be eternally grateful. Please?
