Beware.  This isn't pretty, but maybe it can get you started.

$ more test.html
<html>
<head><title>test</title></head>
<body>
some text with some pictures<br>
<img src="images/joe.jpg" alt="a picture of me, joe"><br>
<p>more text</p>
and another picture <img src="images/joe2.jpg" alt="i'm so handsome">
</body>
</html>

$ grep img test.html |\
sed -e 's/.*src="\(.*\)".*alt="\(.*\)".*/\1        \2/'|\
awk -F/ '{print $NF}'
joe.jpg a picture of me, joe
joe2.jpg        i'm so handsome

First I grab the lines from the file with img in them (hopefully, that's
only the <img src="blah"> stuff.  Then with sed pull out the stuff
between quotes after src and alt and separate them with a tab.  Finally
print the final field with awk (everything after the last /).

Good luck,
JOe
