Image Captions for Portfolio and Blog

Is there any possibillity to include captions on the images shown on those two content structures?
These pages content structure are implemented in the custom template under templates can open the template file then put title any where you want. Thanks.

@jimmy. Could you elaborate more for newbies please?

I added/installed/enabled the image_field_caption module.  Then created a portfolio content type > add existing image field [Select: image:field_image] > save > edit image > select: Enable Caption (alt too for screen readers/visually impaired accessibility). Upload image using your new content type > enter caption in field.
