it's working fine using glide getting bitmap images.

private void applyProfilePicture(EmployeeViewHolder holder, List<AllRestaurantList> dataList, final int position) {
        if (!TextUtils.isEmpty(dataList.get(position).getImage())) {

            String imageBytes = dataList.get(position).getImage();
            byte[] imageByteArray = Base64.decode(imageBytes, Base64.DEFAULT);

            Glide.with(context)
                    .load(imageByteArray)
                    .asBitmap()
                    .into(holder.ivResIcon);

            /*Glide.with(context)
                    .load(dataList.get(position).getImage())
                    .thumbnail(0.5f)
                    .crossFade()

                    .diskCacheStrategy(DiskCacheStrategy.ALL)
                    .into(holder.ivResIcon);*/
           // holder.img.setColorFilter(null);
            //holder.iconText.setVisibility(View.GONE);
        } else {
            holder.ivResIcon.setImageResource(R.drawable.ic_perm_identity_gray_24dp);
            //holder.imgProfile.setColorFilter(dataList.getColor());
           // holder.iconText.setVisibility(View.VISIBLE);
        }
    }

As mentioned in the comment's link If you have converted your image to string by using Base64. You should convert it back with Base64.

Im using this snippet maybe it helps u too.

byte[] data = Base64.decode(iconString, Base64.DEFAULT);
Bitmap imageBitmap = BitmapFactory.decodeByteArray(data, 0, data.length, null); // null for options
imageView.setImageBitmap(imageBitmap);
