Limit the size of an image from ACF

Replies: 0

How can I limit the size of these picture in this repeater code? I want to limit the height of the image. Most code examples I can find are modifying the url of the image html code, but in this repeater code in the page there is no html.
I tried adding to the div style max_height:150 and it does limit the height of the div, but it crops the picture. I’d like the picture resized to fit.

[repeater staff_listing]
<div class="alignright">[if field=picture][field image=picture][/if]</div>
<b>[field name]</b>
[field title]
[if field=email]<a href="mailto:[field email]">[field email]</a>[/if]
<div style="clear: both;"></div>
