When I try to upload my site, all my images are X's.
How do I get them to load correctly?
They are a few reasons that this could happen. The most
1. You're attempting to use a .bmp or .tif or other
non-supported file format. You can only use .gif and
.jpg on the web. You must convert files that are not
.gif or .jpg into a .gif or .jpg with your
2. You've forgotten to upload the graphic files.
3. You've incorrectly linked to the images. When you are
starting out, try just using the file name in the <img>
tag. If you have cat.jpg, use
4. Image file names are case-sensitive. If your file is
called CaT.JpG, you cannot type cat.jpg, you must type
CaT.JpG exactly in the src.
5. If all of the above fail, re-upload the image in
BINARY mode. You may have accidentally uploaded the
image in ASCII mode.
Is there a site that shows which tags work on which
There have been several attempts to do this, but I'm not
aware of any really good source of comparisons between
the browsers. The trouble is that there are many
different versions of each browser, and many different
tags. All current browsers should support the tags in
the official HTML 3.2 specification, but the major ones
also support nonstandard tags and sometimes have
slightly different implementations. One place that has
fairly good compatibility info is Browsercaps.
Why does the browser show my plain HTML source?
If Microsoft Internet Explorer displays your document
normally, but other browsers display your plain HTML
source, then most likely your web server is sending the
document with the MIME type "text/plain". Your web
server needs to be configured to send that filename with
the MIME type "text/html". Often, using the filename
extension ".html" or ".htm" is all that is necessary. If
you are seeing this behavior while viewing your HTML
documents on your local Windows filesystem, then your
text editor may have added a ".txt" filename extension
automatically. You should rename filename.html.txt to
filename.html so that Windows will treat the file as an
How can I display an image on my page?
Use an IMG element. The SRC attribute specifies the
location of the image. The ALT attribute provides
alternate text for those not loading images. For

Why do my links open new windows rather than update an
If there is no existing frame with the name you used for
the TARGET attribute, then a new browser window will be
opened, and this window will be assigned the name you
used. Furthermore, TARGET="_blank" will open a new,
unnamed browser window.
In HTML 4, the TARGET attribute value is
case-insensitive, so that abc and ABC both refer to the
same frame/window, and _top and _TOP both have the same
meaning. However, most browsers treat the TARGET
attribute value as case-sensitive and do not recognize
ABC as being the same as abc, or _TOP as having the
special meaning of _top.
Also, some browsers include a security feature that
prevents documents from being hijacked by third-party
framesets. In these browsers, if a document's link
targets a frame defined by a frameset document that is
located on a different server than the document itself,
then the link opens in a new window instead.
How do I get out of a frameset?
If you are the author, this is easy. You only have to
add the TARGET attribute to the link that takes readers
to the intended 'outside' document. Give it the value of
In many current browsers, it is not possible to display
a frame in the full browser window, at least not very
easily. The reader would need to copy the URL of the
desired frame and then request that URL manually.
I would recommend that authors who want to offer readers
this option add a link to the document itself in the
document, with the TARGET attribute set to _top so the
document displays in the full window if the link is
How do I make a frame with a vertical scrollbar but
without a horizontal scrollbar?
The only way to have a frame with a vertical scrollbar
but without a horizontal scrollbar is to define the
frame with SCROLLING="auto" (the default), and to have
content that does not require horizontal scrolling.
There is no way to specify that a frame should have one
scrollbar but not the other. Using SCROLLING="yes" will
force scrollbars in both directions (even when they
aren't needed), and using SCROLLING="no" will inhibit
all scrollbars (even when scrolling is necessary to
access the frame's content). There are no other values
for the SCROLLING attribute.
Are there any problems with using frames?
The fundamental problem with the design of frames is
that framesets create states in the browser that are not
addressable. Once any of the frames within a frameset
changes from its default content, there is no longer a
way to address the current state of the frameset. It is
difficult to bookmark - and impossible to link or index
- such a frameset state. It is impossible to reference
such a frameset state in other media. When the
sub-documents of such a frameset state are accessed
directly, they appear without the context of the
surrounding frameset. Basic browser functions (e.g.,
printing, moving forwards/backwards in the browser's
history) behave differently with framesets. Also,
browsers cannot identify which frame should have focus,
which affects scrolling, searching, and the use of
keyboard shortcuts in general.
Furthermore, frames focus on layout rather than on
information structure, and many authors of framed sites
neglect to provide useful alternative content in the
NOFRAMES element. Both of these factors cause
accessibility problems for browsers that differ
significantly from the author's expectations and for
Do search engines dislike frames?
Search engines can link directly to framed content
documents, but they cannot link to the combinations of
frames for which those content documents were designed.
This is the result of a fundamental flaw in the design
Search engines try to provide their users with links to
useful documents. Many framed content documents are
difficult to use when accessed directly (outside their
intended frameset), so there is little benefit if search
engines offer links to them. Therefore, many search
engines ignore frames completely and go about indexing
more useful (non-framed) documents.
Search engines will index your <NOFRAMES> content, and
any content that is accessible via your
