What are you talking about? Want to upload camera pictures to your PC directly?
If so, merely plunge the camera to your PC and try to copy and paste the desired images to your computer.
However, if you only want to upload some pictures that had been deleted for 3 months, the best way for you right now is to try some phone memory card deleted photo recovery apps searched online, like
Recuva-100% freeware
iCare Data Recovery Free-100% freeware
PC Inspector
TestDisk
And always save camera photo backups all the time, if you do not want to get such problems again.
Back up, back up!
