Lightbox - smaller imgs in post, larger when click
 

Simple to set up, they are everywhere on the internet as lightbox, shadowbox, imageviewer and so on.

Asking because I saw my pictures breaking the layout of the site, and I don't have time to resize them myself, because I need to fix my car. Yep.

Also it is so easy to miss the text in between the pictures when they are 3500x2500px and the text is 14px tall.
