image sizes on web page/alt tags

Hi all,

1.  Is it true that a page will download faster if I put the size attributes
on each image?  Recently when I ran one of my pages through a validator the
lack of sizes came up as errors.  If I needed to correct this, I would have
to bring each and every image file from all my pages into PS or PSP to view
the sizes and enter them all by hand.  Ugh!  Would there be an easier way to
do this and is it really necessary?  I have some very graphics heavy pages
out there.

2.  I have some alt tags on buttons on one of my pages.  Although I have set
the text as black and links as blue.. and vlinks as black, these alt tags
persist in showing up in green... and it's not a very readable green...it's
a pale green.  The URL is:

How can I get rid of the green on my alt tags?  I want them to be black.

3.  I recently put up a portfolio page showing some of my work.  On this
page my alt tags don't view properly.  Instead of showing the longer
description of each image, the tag is truncated to just one word.  Could
this be my provider, or is there something I should do to fix this?
