Need help in a conditional html test

[Cogito]

A daily graphic from another site is replicated in a page I'm building
like so:

<img src="http://www.---.com/pics/pic1.jpg">

The graphic, in the origination site changes several times a week and
always has the same file name, say, pic1.jpg. The problem is that on
certain days the graphic is not posted on the originating site at all.
This causes an ugly not found icon to show up in my page.

My question is: Is there some simple code that I can place around the
<img> tag that will test if the image is there. If there, display it
as before. If not, display a message 'image unavailable'.

No offence, but that sounds like you're hotlinking to a site that's
not yours.

Probably serverside, but not in the HTML.

Not quite sure what hotlinking is. Basically, I display the graphic
from the other site and a click on it will take the user to that site.
Is this considered wrong?

I just did a Google search on hotlinking. I do understand now what it
is and why it is frowned upon. I'll change my code to not do it
anymore. Thanks you.

If you don't have permission from the site? Generally yes.
