Hi lexi,
You can accomplish this by using the "Customize an Auctiva Template" feature on our website. In order to modify one of our templates to use a custom image arrangement, please log into your Auctiva account and select Listings(tab) -> Customize an Auctiva Template. Then choose the template you would like to modify from the template list and click "Go". This will take you to the template editor page.
Then, click "Switch to Design Editor" above the template editor. Under the heading description, you will see a template tag that reads [DESCRIPTION_AND_IMAGES]. Delete this template tag and and put a [DESCRIPTION] tag in it's place by placing your cursor in the appropriate place and clicking the "Description" link on "Custom Template Tags" menu on the left hand side of the page. This is where your description will appear within your template.
Next, you will want to specify where the images are to be placed within your custom template. To accomplish this, add the appropriate image tags to your template by placing your cursor where you would like each image to go, and clicking the "Image 1", "Image 2", "Image 3" links etc. on the right hand side of the page until you have added as many image tags as the maximum number of images you'll use in a listing. Once you have done this, name your custom template, and click "Save as New" at the bottom of the page.
You will then be able to locate this template in your Auctiva template library under the category "Custom".
