Hi Antonio, manually placing the file on each computer is not necessary, and it won't work. Crowdrender automatically uploads your blend file to each machine when you connect. But, it can't upload external dependencies. You need to pack the texture into the blend file, then connect. Once connected, you'll need to press the "resync" button to force crowdrender to upload the file a second time. This should upload the blend file with the texture inside it and you should no longer have the pink missing texture problem :)
