The fix is to display the piece images not as content of the table cells, but as background.
I saw you doing that for Interactive Diagrams and applied this solution to the Square CSS format. But I did not apply it to the Square Table format, because this is supposed to be an HTML format that will continue to work with older browsers. So, to fix this, I have employed an entirely HTML solution.
The solution in place now is that it reduces the height and width values in the img tag used to display a piece that is too large for the square size. The maximum height or width a piece may now have in the Square Table format is ten pixels less than the $height and $width values. I had to work out some kinks with pieces displayed with showpiece.php. The getimgsize() function, an alternative to GD's getimagesize() function that will work with script-generated images, was not using the correct file name, and I corrected that.
The problem is that browsers refuse to fit 50x50 images in 50x50 cells, because they align the bottom of the image with the text line it is on, and text lines need extra space below them for the 'true descenders' on letters like j, p and q.
I don't think this is true. Each piece image is centered in its table cell. The problem was that when borders are used to highlight pieces, the borders sometimes extend beyond the size of the table cell, causing it to expand in size. By putting a cap on the size of the images, I have stopped this from happening.
