Right now either they are from Wikipedia, or they are from one of the stores selling plants. I have been reaching out to many stores to request permission to use their images in this way and luckily a few have been kind enough to grant it. Those are the images I use. If you scroll down far enough though you will see there is still a need for many more.
Awesome!! Surprised I didn’t know that as I’ve explored plantnet in the past. I’ll add those in!
Could you use AI to generate images for those you don't have a real photo of yet?
I experimented with that few months ago and it was very bad unfortunately. Though it may have improved. Probably for common plants it would work excellent (bell pepper, monstera) but most of the plants on the site are fairly obscure, especially the ones without images. I wouldn’t want to create a misleading image. Another AI approach might be to create simple illustrations of plants I don’t have images for, using other images as reference. I haven’t explored that yet!
