No. You can put images in cells. I do it all of the time for Email advertisements.
If you're doing it for email ads, it's best to upload the images before linking them, because some emailer clients will break the link of the image. Here's table based email page from me for you to check out the code of:
<td width="180"><img src="sleepbag.jpg" alt="US GI Modular Sleep System "MSS"" width="180" height="155" /></td>
<td style="font-family:Verdana, Geneva, sans-serif; color:#333; font-size:12px; padding:5 10 10 10">
<div align="center"; style="padding-bottom:10px"><strong style="font-size:16px; font-weight:bold;">US GI Modular Sleep System "MSS"</strong></div>
Never wake up cold and wet again! This is the real deal, not an imported after market product that has been showing up in other surplus stores! This U.S. G.I. four part modular sleep system was designed to be used together for temperatures as low as -30°. Here's what's included... One Compression sack (black) for compact storage, one cold weather patrol sleeping bag (black), one intermediate sleeping bag (olive), and one Waterproof/Breathable Bivy cover (woodland camouflage) to keep the whole system dry. This system was designed in layers to trap in pockets of air and heat. The complete system, including the compression sack, weighs roughly twelve pounds. Compare our pricing to others, selling for up to $400.00. Made in the U.S.A. Some compression sacks may have imperfections. Used, Good Condition.<br /><br />
