Hi,
May I know in the first place what are you trying to achieve? The solution you are using at the moment does not make any sense to me.
CMSEditableImage control stores the images on current document [CMSDocument table, column DocumentContent] (on document where your repeater sits) and with the repeater you are displaying (I guess) content from some other documents from your content tree (of course, if you are using Kentico
CMS repeater and not the standard .NET repeater – this was not mentioned in your description). Wouldn’t it make more sense to keep the image as part of the documents (let’s say to add custom field to your document type of type file) you are displaying/listing with the repeater?
Thanks,
Miro
