Reglas obligatorias:

Crear una carpeta llamada proyectos.

Guardar las imágenes dentro de esa carpeta con el siguiente formato:

caso1.jpg

caso2.jpg

caso3.jpg

caso4.jpg

No duplicar imágenes.

No reutilizar la misma imagen en más de un caso.

No inventar imágenes nuevas.

Cada caso de estudio debe:

Usar únicamente las imágenes asignadas a su número de caso.

Mostrar las imágenes como resultado visual principal.

Respetar el orden correcto de las imágenes.

Si hay más de una imagen por caso:

Usarlas en una galería limpia

Con buen espaciado

Sin superposición

La carpeta proyectos debe ser la única fuente de imágenes para los casos de estudio.
