images in tables

[NeilBelgium]

dear all, although I can create semi-decent data related pages, I still am having problems with web design!
I've downloaded our website (created by someone else years ago!) onto DW Ultradev, and I am trying to amend some pages. the main problem is with inserting images:

I have created a table (5x2) and am intending to put fiove photos of people in the left column.
There is a link to the image source (assets/image) and all images are gif. or jpeg. However, they don't seem to be recognized.
If I try to open them in Fireworks, I'm getting an "unknown file format" error.

I know this is meant to be simple stuff, but what is the standard way to approach?

any ideas most welcome, many thanks, neil

If you are receiving an "Unknown file format" message in Fireworks when attempting to open the images that means that either:

1. The images aren't what the extension says they are (i.e. the extension is .gif but the image is actually a .tiff) or

2. The image file is corrupted.

Do you receive this error message for every image or just some. Also, have you tried using IE or another image editor to view the files?
