This page demonstrates three bugs in Mozilla 0.9.2. First, the following two tables demonstrate that specifying HEIGHT and WIDTH on the IMG tag affects layout.
This is a table. Each of the following two rows has a single, left-aligned image in it. The difference between the lines is that the second specifies 'WIDTH=5 HEIGHT=5' on the IMG tag. The image really is a 5x5 square, so the HEIGHT and WIDTH attributes should have no effect on the layout. However, the second row has a extra pixel on top and bottom of the image, and this increases the height of the table row by 2 pixels.

This table is similar to the first. However, the images in this table have 'ALIGN="right"' specified. The second row has additional height, like the example above. In this test, the second image is shifted 2-3 pixels to the left.

The second bug is that the NOWRAP attribute interacts with HEIGHT, WIDTH, and ALIGN.

This one is even weirder. Specifying the image's HEIGHT and WIDTH, as well as putting NOWRAP on the TD tag, makes the image be left-adjusted. However, the last image isn't as far to the left as the left-adjusted images in the first table.

The third bug involves redisplaying this page. To duplicate the bug, view this page and note where the black squares are. Right-click on one of the black squares and select "View Image" from the context menu. After admiring the black square :-), press the Back button to return to this page. The position of several of the squares has changed. Pressing Reload will restore the previous positions.
