After I deleted gallery, I no onger have internet.

Can I get internet connection back without erasing my SD card?
I transferred photos from phone and then checked the gallery and found photos and downloads that were blank. I selected all and deleted to free up space and then, no internet.

Your SD card and pictures should have nothing to do with having an internet connection, loosing it at that time was probably coincidental. Check if other devices at your location have an internet connection, PC other phone etc. If not check if your router is operating. If the internet is available try "forgetting" your connection and resigning on using your password..
