Ayuda con codigo JavaScript para plantilla blogger

Buenas, parece ser que el codigo JavaScript, engloba como se ve el estilo del titulo del post, tamaño de imagen, etc. El problema es que la imagen se ve muy apliada, como si tuviera zoom, y la imagen no se ve entera, se corta por los lados. Y yo quiero la imagen en tamaño original.



Es decir, Titulo post, imagen con sutamaño original, un poco de texto, y ya para leer mas del articulo hacer clic en leer más.Este es el codigo JS que hay puesto:

No sé como podría modificar el codigo para que la especie de zoom que hay puesto en la imagen se quite y se vea a tamaño original, porque no se ve entera la imagen.

Saludos.

Lo mas probable es que sea un problema con la hoja de estilos que javascript.
El codigo que muestras esta ofuscado, hay herramientas online que lo desbloquean pero como te digo, no creo que ese sea el problema.

Edito:
Quizás sí sea por ese javascript, prueba cambiando los valores del final:
thh = 420;
thw = 674;

O comentándolos:
//thh = 420;
//thw = 674;

Si no, deberías revisar tu configuración de blogger porque al publicar te está recortando las imágenes creando un nuevo link para éstas.

loquendomia Gracias! He probado lo que dices, pero pasa lo mismo
