I need some quick assistance with images being put together with no margin between them anywhere. which CSS is overwriting this default/standard of having a space between images??

There is actually no CSS that provides an image spacing or margins at all. Adding a margin could be detrimental to the overall layout as well as it would affect all images depending on how it was coded. What are you looking to space precisely? Images in posts?

exactly. Images in post first and foremost

Having no margin is sort of industry standard in case you do want no space. You can add space in many other ways. But if you want space between images in a post add this to your custom.css:

.ipsType_richText img {
	margin: 8px;
}

 

excellent! looks great now!!! thank you!

You're welcome.
