Cancelar inclusão de imagens via java

[Alex_tm 0]

Boa tarde!

 

Estou trabalhando em um projeto de personalização de um portal e algumas imagens são inseridas via javascript. Preciso cancelar a inclusão dessas imagens, porém o meu conhecimento em java é muito superficial.

Alguém poderia me dar uma orientação?

 

Agradeço antecipadamente a atenção de todos.

 

Segue o código

Lugar errado amigo, esse fórum é de Javascript.

[Alex_tm 0]

Marcelo, bom dia.

 

É, estou realmente perdido neste projeto.

Isso é Ajax?

 

Obrigado.

[Marcelo Lipienski 9]

Isso é WebForms, um framework da Microsoft criado em cima do Javascript para criar aplicações .Net usando o famoso método drag&drop (clica e arrasta o componente para o canvas).
