I have been using picture URLs to add signatures to a pdf doc. I just got a phone call that the images no longer show up. I have been using this for a few years without issue. When I went into the spreadsheet to look, when I click on the url, is says Bad Request.
thanks steve. Now the URLs are working again. The =IMAGE cell next to it is still not showing the signature? =if(isblank(EP1879),"",IMAGE(EP1879,2))
