DW,
As an MCITP these are not false hits. We have had one person infected/damaged and I have had it happen to me. My AV stopped it and warned me.
When you try to view the images/links you get AV8 virus.
What is av8 scan? The av8 virus causes computers to show fake av8 scan so non suspecting pc users may be lured to buy the virus av8 anti-virus, av8-scan malware. You can Google "AV8 virus" for more information.
I don't think this is an issue with the members that use Image Shack but rather a problem on Image Shack side.
This is a very serious issue and as always I will err on the side of caution. Sorry for any inconvenience.
