Just one more thing...

... on my computer, some of my most recent photos look like the resolution isn't high enough to make them sharp. And it's happening almost exclusively with colour photos, not B&W. Not sure why this is happening, as I'm not doing anything differently these days in terms of uploading or hosting. Please help me out and tell me - do the photos show up clearly for you, or is there some grain to them? I don't know if it's just me or if we're all having trouble viewing them.
