Exibir Imgem no Grid

Paulo Silva 16/01/2019 (há 5 anos)

Pessoal, criei no Adianti Studio um cadastro de categorias e neste tem a opção de incluir uma imagem. O Upload é feito normal, onde constatei a existência da imagem na pasta tmp do meu servidor e na tabela gravado o nome do arquivo como segue (van_sat203x54.png). Mas não está aparecendo a imagem no gri da listagem. Alguém ajuda por gentileza.
Segue abaixo o código da Listagem de Categorias:
