Hmm...I just did something similar using EE. Try something along these lines:
<div style="<?php static_pblock("YourGroup","YourPBlockImage");?>">
<?php static_pblock("YourGroup","YourPBlockText");?>
<div>
Uh oh, just re-read your message. Both the text and image in the same pBlock seems like it would require more HTML in the pBlock which isn’t non-tech friendly. Sure you can’t seperate them into seperate pBlocks?
Uhg....used to be I had trouble wrapping my head around EE from pMPro. Now I’m having a hard time going backwards. pBlocks don’t seem inherently “client friendly”...maybe look into using a weblog instead, with one of the custom fields storing the image?
