Problemas na salva de imagens - Upload de imagem no TFile

Sergio Rodrigo Silva 26/10/2017 (há 6 anos)

Pessoal, é o seguinte!

Estou fazendo uma implementação de acordo com os exemplos do Tutor.
Mas por algum motivo (ainda não descobri qual), a imagem não carrega para meu campo Image.

Ao tentar salvar o registro dá o seguinte erro:

Fatal error: Class 'finfo' not found in C:xampphtdocsctrlarmasappcontrolDivulgacaoForm.class.php on line 126

Em anexo, segue como fica a tela após carregar a imagem, e abaixo segue o código da pagina!
