you're not using file system intended dnn. images should managed through dnn's dotnetnuke.services.filesystem namespace , you're writing lot of code don't need in order save images (try dnnfilepickeruploader control, handles upload , passes fileid). once have fileid persisted object, use load image:

private string getpath(int fileid) {     stringbuilder sb = new stringbuilder("/portals/");      ifileinfo fi = filemanager.instance.getfile(fileid);     sb.append(fi.portalid);     sb.append("/");     sb.append(fi.relativepath);      return sb.tostring(); }
