Mariia, it seems odd that it's up to me to parse "./" when it's a supported Kentico path expression. there's no api method for resolving these supported expressions? https://docs.kentico.com/k8/developing-websites/loading-and-displaying-data-on-websites/loading-document-data/writing-document-path-expressions
Brenden, I don't think SectionImage would be using a relative path, so I'm unclear how this is related.
