So tell me if you can make from a JPG or PNG format with a batch process 300% ?
so I can transform eps on any format you prefer
make also 300% will be not practical because file will be too big for uploading
300 % = 500 kb * 1953 = 1 giga!
100% = 75 KB * 1953 = 150 megas!
Ps Seems you have send twice the sames files! 
What format do you want?
And I don't understand very well advantage to have thousand of files * 300%
Any modeler can make a background image * 300 % directly
And you can't modelize 2000 models in the same time!
