Re: CSS works in FF and Chrome but not IE …
In all honesty this isn’t the appropriate element to use for a list of thumbnail images; tables are for tabulated data which a series of images isn’t, these should really be a ul li which ultimately you will find easier to style and control.
If you’re persevering with the table then I would suggest you create a Conditional Comment file for IE 8 or perhaps [IE lte 8] and run some checks for IE 7.
The issue looks to be Modern browsers shrinkwrapping the tr/td to the content width i.e the image whereas IE is creating a td that adjusts to the table width. You could use a fuller set of table attributes and specify cols and their widths but this is getting into advanced table constructs.
