Bumble reply when she opened with a compliment about your photos

Her compliment is only the first line, so look at what came with it. If she mentioned a specific photo, a specific detail, or something from your bio, she paid attention, and you can build on that exact thing. If the message was generic, like "you look nice" with nothing else, she is probably running through matches quickly and the opener carries little weight.

Check her own profile before you reply. A climbing trip, a pet, a city she lives in, or a prompt she answered gives you a second thread besides the compliment. Her compliment tells you she is open to talking. Her profile tells you what she would actually want to talk about. Neither one alone is enough to build a good reply on.

Accepting the compliment in a single short clause is enough. Anything longer starts to sound like you are waiting for more praise. The move that works is to take the compliment and then immediately give her something to answer, ideally tied to the photo or detail she mentioned. A question about where the photo was taken, what the trip was like, or how she got into the thing on her profile is easy to reply to and gives her a reason to keep going.

Keep the question open enough that a one-word answer does not end it, but simple enough that she can answer in a sentence. Avoid questions that are really compliments in disguise, and avoid anything that asks her to evaluate you. You are trying to get her talking about something she already cares about.

Most openers like this should get a reply within a few hours, while the conversation still feels live. Waiting until the next morning is fine if you are both on the app at different times, but a multi-day delay usually means the moment has passed. If you are answering in the evening, a short, easy message is better than a long one that tries to make up for the wait.

If she replies, match her pace and keep the conversation going for a few exchanges. If she does not reply after you have sent a reply, leave it alone for a couple of days. One gentle follow-up tied to something new, like a question about her weekend, is reasonable. After that, stop. A thread that goes quiet after a compliment opener usually went quiet because she was matching many people at once, not because you said the wrong thing.
