Text her same day, something funny like "Hey it's ashraf, that _____ guy you met at _____". Try to fill in the blanks with specifics from the convo. If you were funny, go with "funny guy". If it was a boring convo and you can't think of anything interesting (in which case evaluate your approach banter), say something like "sexy guy". Text it within 1 hour of leaving sight, so she has your number and remembers you. This builds rapport, in the same way a venue switch does. Now she's effectively had two contacts with you, but you've invested nothing in this second contact. Wait a few days (builds suspense), then text again, saying "Hey ____, how are you?" After she replies, usually she'll ask how you are. Reply "good, wanna go to ____ for drinks?"
You rushed it by inviting for the same day. She's either actually busy or punishing you for being needy.
In answer to your question, I'd use a combo of the above advice: Send a picture in a few days of where you're at, make it interesting. Add a description of where it is, and say "how are you today?" When she replies, ask her if she'd like to get a drink on _____ (some day when you're free, not the same day). If she doesn't reply at any point or says she's busy without giving an alternate date, delete her number and move on with your life.
