I was thinking I should find a way to do this in just css, and not add the complication of markdown, and found this link. Thought I should shar with other SS designers. 
 

Thank you! Using your guidance and Heather Tovey's amazing ID finder I am soooooooo thrilled with the results! Yup, I will be back for other help! 
How do I mark your answers as Best?
Thank you again!
 

To target more image blocks add selectors. Like...
#block-xyz, ( comma after the selectors except for the last line )
To find image block ids check out Heather Tovey's most excellent looking Squarespace ID Finder.
If you need to target images other than image blocks we'd need to see the other images to know what selectors to use.

Remove previous attempts at this effect.
Add the following to Design > Custom CSS.
#block-yui_3_17_2_1_1611536090911_13771, #block-yui_3_17_2_1_1611536090911_15064, #block-yui_3_17_2_1_1611536090911_5435, #block-yui_3_17_2_1_1626279894886_78956   {        padding : 0;          } This is for v7.0 using the Brine template family.
If you delete or add blocks then you'll need to update the block id selectors. Notice the last selector doesn't get a comma after it.
Let us know how it goes.

Most likely yes. We'd need to know which specific image you want to remove the padding from.
