Creating space around your images is done using HSPACE and VSPACE.
The example below shows 3 images without any spaces-

To make spaces between the images we add HSPACE to the image tag so that it looks like this-

Here's the HTML

<IMG SRC="http://www.yourimagehost.com/yourname/yourpicsname" HSPACE="10">
<IMG SRC="http://www.yourimagehost.com/yourname/yourpicsname" HSPACE="10">
<IMG SRC="http://www.yourimagehost.com/yourname/yourpicsname" HSPACE="10">

To make spaces between images in a verticle line we add VSPACE to the image tag so that it looks like this-

Here's the HTML

<IMG SRC="http://www.yourimagehost.com/yourname/yourpicsname" VSPACE="10">
<BR>
<IMG SRC="http://www.yourimagehost.com/yourname/yourpicsname" VSPACE="10">
<BR>
<IMG SRC="http://www.yourimagehost.com/yourname/yourpicsname" VSPACE="10">
