That’s probably just our fault for posting wider-than-screen images. There’s a real trade-off if the image is hot-linked and auto-updating like the JTWC storm paths. It’s very valuable to hot link them so that they update by themselves; that way we don’t have to keep accessing, saving, uploading and linking the images. On the other hand, they cause the problem you mentioned.
Once the image shrinks, the page returns to normal, so I think it’s acceptable.
The alternative is to use something like the free MWSnap screen capture utility to save only the left-hand storm path image, separately capturing the windspeeds etc. on the right side. That way the image is narrower, but it’s twelve times as much work (x2 to do both sides, x6 to upload about six times over the course of the storm’s progress). So having a stretched screen in this one particular thread is acceptable, to me.
Sure, if there’s some way our whiz-kid admins can reprogram it so the image is automatically resized to a certain maximum, that’d be great!
