Some users having difficulty seeing images

[SherryG]

Hiya guys,

I have a couple of users telling me that some (not all) of the thumbnails in my gallery are showing up as the dreaded red X instead of the graphic thumbnail. The odd thing is, most of us users, myself included, see the actual thumbnails. They are displaying properly

Might someone be able to shed some light on this? Why would some users be able to see only some of the gallery thumbnails and not others. Why do most users have no issues with the gallery while others do?

Thanks!
Sherry

I really can not say but example urls might help here. What site is this we are talking about.
