Help with a HTML Tumblr Theme?

This is so embarrassing, but I don’t know where to ask.

I’m hoping it is indeed HTML.

I have a personal tumblr and I’d like to remove some things from my ‘theme’. When you reblog posts it leaves the name of the person I posted from and a bottom footer of the date or other information.

I’d like it to be just photos/pictures and no text.

I just have no idea where to ask. Could someone point me in the right direction?

Thank you.

I got this because of my talent,…
