Image extensions
There are multiple formats of images. Each
format has a different file extension. You
can use them as src (source) for <img> tag
 Image.gif
 Image.jpg
 Image.png
 Image.bmp
 Image.tiff
Images
 <img
…./> - <img> (image) is the element
used to embed images
 <img src="smiley.gif" /> - src (source)is an
attribute of <img> which provides path to
the image being embedded. It embeds
an image file “smiley.gif” from the same
directory as the html file.
Images
 <img
src=“c:\webdesign\newpic.gif" />
Embeds an image file “newpic.gif” from
directory c:\webdesign
 <img
src=“\\server\webdesign\anotherpic.gif" />
Embeds an image file “anotherpic.gif” from
the directory \\server\webdesign
Images
 <img
src="smiley.gif" width="32" height="32“
alt=“smile”/>
Width and height attributes of <img> decides
dimensions of embedded image. Only use one
of these so the image doesn’t stretch.
 The alt attribute provides alternative information
for an image if a user for some reason cannot
view it (because of slow connection, an error in
the src attribute).
