Existing studies focus on aesthetics or object presence but overlook the functional balance among image types. This study introduces the Holistic Image Proportion (HIP)\u2014the ratio of holistic to detailed review images\u2014as a key determinant of visual information completeness. Using deep learning (ResNet-101) to classify over 240,000 images from 4450 clothing products, we find an inverted U-shaped relationship between HIP and sales: a balanced mix (HIP \u2248 0.5) maximizes performance. A follow-up experiment confirms that balanced image composition enhances perceived completeness, which fully mediates its effect on purchase intention. Review sentiment further moderates this relationship, amplifying the effect under positive sentiment. This research extends information completeness theory to visual data, highlighting that completeness emerges from functional image composition rather than quantity or aesthetics, offering new insights for multimodal persuasion and e-commerce design.<\/jats:p>","DOI":"10.3390\/jtaer21010018","type":"journal-article","created":{"date-parts":[[2026,1,5]],"date-time":"2026-01-05T10:03:48Z","timestamp":1767607428000},"page":"18","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Beyond Aesthetics: Functional Categorization and the Impact of Review Image Composition on Purchase Decisions"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-3727-3739","authenticated-orcid":false,"given":"Minchen","family":"Wang","sequence":"first","affiliation":[{"name":"School of Management, Zhejiang University, Hangzhou 310058, China"},{"name":"Center for Research on Zhejiang Digital Development and Governance, Hangzhou 310058, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Tong","sequence":"additional","affiliation":[{"name":"School of Management, Zhejiang University, Hangzhou 310058, China"},{"name":"Center for Research on Zhejiang Digital Development and Governance, Hangzhou 310058, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Dong, H., Park, K.K., and Kim, J.M.
