Hello westshorecc -
if your primary concern is to be compliant with the eBay links policy, the tool we have running for all accounts will remove the link to the old supersize page from active listings that are eligible for revision on eBay. The images would no longer supersize since that functionality is no longer allowed by eBay, but the links themselves will be removed where possible.
If you wish to have the new version of the supersize images added to your listings, please be aware that the new functionality does comply with eBay's new links policy and these images do not require a link to display. However, it is tied to the use of our new templates, so one of these templates would need to be applied to your listings for the images to supersize. At this time, we have no tool that is able to change out or add a template to an already active listing, so the steps for taking care of this on a listing by listing basis are the correct ones.
You can apply templates to Saved Listings in bulk if you wish to end active listings and then post them again from your Saved Listings using one of the new templates
Our engineers are looking into creating a tool that would allow templates to be added to already active listings and I will update this thread as soon as more information regarding such a tool becomes available.
