Dynamic Content - Images - URLs

hello.

I want to be able to have a dynamic URL attached to an image but not have the image in the dynamic component library

example of what i have now:

<a href="mysite.com/landingpage?elq=~~eloqua..type--emailfield..syntax--recipientid~~&elqCampaignId=~~eloqua..type--campaign..campaignid--0..fieldname--id~~"><img src="http://images.email.mysite.com/EloquaImages/clients/mysite/{0723455ad89ec-fc95-480d-b155-a886512bbe23}_imagename.jpg" width="226" height="39" alt="get it now" border="0"></a>

at this time i have 5 images that i want to link to a landing page.

i want to be able to have one link to change only instead of 5 things in the component library

any ideas?

thanks for any help
