You can also try to contact a few local real estate agents in the area and ask them if they wouldn't mind driving by the property and snapping a few pictures when they have a chance. Most agents are regularly in the field anyway, and it isn't a huge ask for them to swing by your property and get some pictures (especially if you show an interest in using them for your future listings and/or paying them a few bucks for their trouble).
If this process overwhelms you, consider hiring a land broker. A land broker will take a commission but they will handle all of the above for you. Hopefully they will price the property so that you make almost as much as you would have without hiring the land broker meanwhile it saves you a lot of time and hassle. I do not recommend working with a land broker who charges a flat upfront fee even if the property doesn't sell as there is no built-in incentive for them to sell the property. Keep on top of them and make sure they are doing their job. Unless the commission is hefty, a land broker isn't going to care as much about selling your land and may end up just listing it on their own website and letting it sit there forever. Communicate regularly with your land broker so your listing remains a priority for them even if it's just to get you off their back!
After identifying your likely buyers, try to think like them so you can focus your message to convey what they need to know about your property. Have information ready about schools, shopping and other nearby amenities. For developable land you can be prepared with zoning information and insight from local authorities about the location and capacity of water and sewer service. Each property is different, so customize your information for your situation and your targeted buyers.
