The mod portal website is currently displaying screenshots with image-rendering: pixelated or image-rendering: -moz-crisp-edges, whichever is supported. This causes the browser to use the nearest-neighbor resampler, which makes text nearly illegible and is otherwise unattractive.

First screenshot from the Helmod page, as it is now:
With correct, default image resampling algorithm:

In the full-width mod portal, images are rendered 840 pixels wide.
So you can work around browser scaling by making your images the same width. Example mod (See second image for a screenshot containing text).

Not sure why that was in place, fixed.
