Answer Title
Answer
Physical Memory The total physical memory, also called RAM, installed on your computer. Available
represents the amount of free memory that is available for use. The System Cache
shows the current physical memory used to map pages of open files. Kernel Memory Memory used by the operating system kernel and device drivers. Paged is memory
that can be copied to the paging file, thereby freeing the physical memory. The
physical memory can then be used by the operating system. Nonpaged is memory that
remains resident in physical memory and will not be copied out to the paging file.

If your images are inside a table, be sure to set the BORDER, CELLSPACING, and CELLPADDING attributes to 0.
Extra space between images is often created by whitespace around the <IMG> tag in the markup. It is safe to use newlines inside a tag (between attributes), but not between two tags.
