When you set an explicit size on WIDTH/HEIGHT in TD fields, these do not get respected ie. the TD field is allowed to change size. When an image gets assigned a percentage in HEIGHT when within a TD, these do not get displayed. http://www.it-c.dk/~morten/mozilla/

height=... for <TD> is deprecated, see http://www.w3.org/TR/html401/struct/tables.html#h-11.2.6 . Should Mozilla support this, or is this INVALID?

Mozilla processes the example page in quirks mode. Quirks mode not working as it should is still a bug. On the other hand, quirks mode was set up to reflect the way Netscape 4 did things, and Netscape 4 I believe has that same problem. So maybe that's a feature, of sorts.

TABLE & TD do not support the height element in HTML 4.0. Images, according to the HTML specs should strech with percentage dimensions. This bug be valid in that case. http://www.w3.org/TR/html4/struct/objects.html#h-13.7.1 Images properly stretch with percentage widths in table cells (they stretch to the percentage of the width of the cell), but they do not accept a percentage height (they simply don't show up. This may be a result of Mozilla considering the height of the cell to be 0, perhaps, and making any percentage of 0, simply be zero?

Further note, style="height: 100%;" caused the image not to appear was well.

Related to bug 41656.

This is bug 74313. The other half is invalid as stated, please keep your bug reports to one bug at time. Thanks for contributing to Mozilla. *** This bug has been marked as a duplicate of 74313 ***

I'm not comfortable with leaving this as a duplicate. After looking at bug 74313, I don't see any relation to tables. Perhaps you could explain what makes this a dup? In this case the image, outside of a TD will actually scale correctly to a percentage height. It's being inside a TD, where presumably, Mozilla is seeing any percentage of 0 pixels as (rightly so) zero. This might have to do more with table rendering than images.
