Como faço para criar um javascript que possa redimencinar automaticamente conforme o tamanho da imagem ? Tenho uma pagina com uma imagem pequena e um link que abre um pop-up com a imagem em seu tamnho real, o problema esta em que no script usado o link é previamente configurado para abrir o pop-up em 400px x 400px, e nem sempre as imagens são neste tamanho, podem variar tanto na autura como na largura para menos ou mais, ou seja a imagem acaba ficando distorcida, já vi em alguns sites pop-up que redimenciona automaticamente conforme o tamanho da imagem, mas procurei tutoriais que pudecem me ajudar a criar um script deste mas não achei nada, então resolvi apelar para o forum. Se alguém souber agradeço.

Olá pessoal,
Como faço para criar um javascript que possa redimencinar automaticamente conforme o tamanho da imagem ? Tenho uma pagina com uma imagem pequena e um link que abre um pop-up com a imagem em seu tamnho real, o problema esta em que no script usado o link é previamente configurado para abrir o pop-up em 400px x 400px, e nem sempre as imagens são neste tamanho, podem variar tanto na autura como na largura para menos ou mais, ou seja a imagem acaba ficando distorcida, já vi em alguns sites pop-up que redimenciona automaticamente conforme o tamanho da imagem, mas procurei tutoriais que pudecem me ajudar a criar um script deste mas não achei nada, então resolvi apelar para o forum. Se alguém souber agradeço.
Obs.: A pagina esta em ASP e busca a imagem em banco de dados que já foi pre cadastrada, abixo link para visualizarem como esta o funcionamento Clque aqui para ver
O código que estou utilizando (são 2 paginas, uma com o link e outra retorna o link)
