I made a trademark with ps, but I can't upload it. The system says that only JPG, GIF, PNG, SWF, RAR, ZIP and XLS can be used.
this is the format. The trademark format you made is not the format recognized by the system. So there will be errors. I suggest that you save it as gif if it is a dynamic trademark format, and jpg if it is static. For that format, set it there, and open the file with ps. Choose to save or save as. Below the file name is the file format. Look carefully and you'll see.
