Signature Image HTML display

Good day,

I use the following deluge script to get url images to catch signatures and display in html reports. I open the report with my developer user and it works perfect, but when another user open the report the signature images appears as a broken link.

I try publishing the report where are located the signatures, but I have the same issue.

imagelnk = FetchRegistro.Firma_Capacitador_1;

imagelnk = imagelnk.replaceAll("/sharedBy/appLinkName/"," https://creator.zoho.com" + zoho.appuri);

imagelnk = imagelnk.replaceAll("viewLinkName","Registro_Formacion_Abiertos");

imagelnk = imagelnk.replaceAll("fieldName","Firma_Capacitador_1");

piclink1 = " https://creator.zoho.com/czambrano1/recursohumano/Registro_Formacion_Abiertos/";

RegistroID = FetchRegistro.ID + "/Firma/image-download/";

piclink = piclink1 + RegistroID + imagelnk;

LinkFirmaC1 = "<img src='" + piclink + "' alt = 'test' height='30%'/>";
