Olá,

Sou iniciante em PHP e gostaria de uma simples ajuda numa modificação q quero fazer no meu fórum em SMF.

Quando se anexa qualquer imagem, no tópico aparece o ícone de um clips q não está cadastrado com os demais ícones no Admin Painel, ou seja, esse ícone é programado para aparecer sempre q alguma imagem é anexada. O q eu quero fazer é tirar a imagem desse clips e programar para aparecer a primeira imagem anexada no tópico e colocar limites de tamanho para essa imagem. Assim, independente da imagem q a pessoa anexar, ela apareça sempre num tamanho padrão de fora do tópico para todos verem.

Se alguém se propor a me ajudar com isso, posso postar os códigos aqui.

Opa, podemos dar uma analisada e ver o que é possível fazer. Se é um mod no sistema, devemos ter cuidado, pois esses sistemas de foruns já utilizam de alguns mods pra auxiliar no desenvolvimento.

Mas pode postar os codigos pra analisarmos com certeza.

Obrigada por se propor a me ajudar \o/

Acredito q não seja um mod do fórum e sim algo q já vem com o próprio SMF, por isso achei mais fácil fazer essa alteração do q tentar criar um mod q faça isso q eu quero. Eu uso o Php Expert Editor, dae fiz uma busca pela palavra "clip.gif" e taí os códigos onde essa imagem aparece.
