Move image titles below the image

Site URL: https://www.jirobevis.co.uk/

Hi,

I'm trying to create my website and am nearly there, however there is one thing that I can't seem to fix.

I want each image to have a title below it in black but the only option I have is to have the title laid ontop of the image in the bottom left corner with a gradient backdrop which I think is really ugly and also onstructs the image.

Is there anyway around this? I've attached an image of how it looks and also roughly how I would like it.

Cheers
