I mainly use offline means: organising all my files in a hierarchy of folders and using pureref (which I highly recommend) to make moodboards, and ofc an external hard drive to save backups. The only online means I use is google drive... Source: about 4 years ago
If you just want the image to be a transparent overlay while you draw 'through the image'(with it being unchanged) you can use something like Pureref(pureref.com) to set the image as always on top + turn opacity down a bit. Source: over 4 years ago
If you can’t get it to work inside of max, I thought of a free easy workaround you could try. I use the software pureref to manage and quickly access reference images. You could just resize an empty pureref window to cover your username.... Source: over 4 years ago
