Point all images for 'projects' and 'publications' to open as 'popout' instead of new tab of only image

[Nikronic]

Currently, by clicking on images in 'open source' and 'publications' section, user will be redirected to a new tab where only image exists.

This is not smooth and annoying as many may want to go into the blog, github or pdf actually. So instead, we create a 'popout' version for all images so they can see image in high quality very fast and easily opt out if they want to go into github, pdf, blog etc.
