Corrupted images
I'm a webmaster for several nonprofit websites. I use HomeSite and Photoshop to create my websites on my Dell laptop running Windows XP.
Several times in the past two years, I've had a problem with some of my graphics suddenly looking corrupted. By that I mean they have dots on the image or parts of the image are misaligned. One day they're fine, and the next some of them look odd. When I look at the corrupted image as a thumbnail in Windows Explorer, it looks fine. But when I open it on my system - usually in HomeSite first - I notice the problem.
I'm very careful about screening for viruses and getting updates, and I've never had a virus problem on any of my systems. When this image problem happens, I write over the file with a new copy and it fixes the problem. I can go many months without it happening again. And it doesn't happen to all my images, just some.
Below is a link showing what one of the corrupted images looks like. If anyone can offer a suggestion as to why this happens, it would be greatly appreciated.

Are these recently uploaded pictures? If so then it is more than likely a problem with them being uploaded via ftp as ASCII not Binary files. This can cause the type of corruption that you mention. Occasionally I have also seen IE not display pictures correctly. Usually a refresh or dumping your cache will fix that.
Welcome to WMF. Good choice of Homesite as your editor.

Thanks for the welcome and the reply, mairving. I've enjoyed lurking here for some time.
I tried clearing the cache but it didn't work. These files are becoming corrupted on my hard drive - not from uploading/downloading. After they're corrupted, if I try to open them in Photoshop, I get a "this file may be damaged or truncated" message, and then it looks corrupted in Photoshop too, so it's not just an IE problem.
I'm just stumped as to why select images are becoming corrupted, and why it's so random.
But much thanks for your help.
