I've seen that rumour on the wiki too, though I don't know who came up with it or why. I know that Dim's .png only policy was based on that. It's probably because most of the .jpgs on the wiki were really poor quality, as the uploaders either used poor quality pictures or just didn't know how to work with jpgs.

.pngs are good in the sense that it's a lossless format, thus even if you get an image in a different format, you could just convert it to a .png without any loss and thus upload a revision for an existing file.

However, when the file becomes large, the .png's size drastically rises as compared to .jpgs. Thus, I guess we should only bother with the .png thing with anime screenshots and small-size files, while use .jpgs for things like magazine scans, official artwork etc., as they usually have a much higher resolution and, thus, overly large .png files.
