I am suddenly getting errors as of yesterday that the image URL is no longer valid when it has been working fine for two weeks. After reading online from some other add-on sites, I tried using a thumbnail and this works. This is too small for the merged document, but at least it works. What is going on and how can I fix it? I have a class of 120 students using this every day and their images are no longer included in the merge.
This array formula =ARRAYFORMULA(if(row(A:A)=1,"photoid",substitute(K:K,"open?","uc?export=view&")))
But this does for the merged document
Please help and thank you in advance!
