image shows on local browser but not after upload toremote server

I am a new Dreamweaver CS3 user.

Just finished my first site which tested out fine locally, but one of the
images does not display after I upload to my host server.

Any thoughts about what I am doing wrong, would be much appreciated.

I included the bit of code.

Thanks in advance for any input.

</td>
<td width="500" rowspan="5" align="center" valign="middle"><img
src="assets/images/Screenshots/home page 90%.jpg" width="532" height="724"
/></td>

Spaces in file names is never a good idea. Got a url?
