I sorry for my poor English

I have a project to show the student`s photo, like this↓ loop on the elements of data.
data is from api

<v-img :src="/img/0001_${info.idcode}.jpg" min-width="75" contain />

I need to set no-img.jpg which the students photo is undefind, so I rty to use @error like this anwser↓ but thiss not work at loops

I noticed lazy-src can instead of @error to show the no-img.jpg when the students photo is undefind, but the lazy-src` has a slight blur filter applied. can I remove it ? and where can I remove it ?

sorry for my poor English again.
