Hi Debs,
You would definitely need to change the syntax. I'm not 100% certain to what. The photo is treated as an attachment and therefore there isn't actually a field. The only way I've done photos that is similar is with a secondary field as well. I always have a caption field with my photos so mine look like.
${if cap_photo1} ${img_photo1 | size:300:0}${/}
That will put the caption before the image but only shows both if the caption has been filled in.
Sorry, I'm not sure what else you could do with the photo option.
