Recently I had an idea to split adopts into categories. I noticed that many buyers prefer certain themes and often buy something similar every time. For example, fantasy, pokemon, anthro birds, etc. It would be great if there was a place that contains a lot of folders/groups which you could click and find only adopts you want to get without having to look through hundreds of others. The easiest way, of course, is to simply distribute adopts into FA folders, but... There are no more folders because they are intended for the shop's artists. So I need a third-party service and I want to ask for your help in finding it.
It should look like this: the user opens the site and sees a list of different folders/groups that they can click on and see the pictures inside, like in Google Drive. Why can't I use Google Drive? Because one adopt can have many different categories and it will be hell to upload the same picture to several folders. (there are 558 images in the "Adopts" folder. And I'm not even mentioning the packs where I'll have to cut out each adopt separately. That would take years!) It would be easier if there was an option to set several directories for one image and it would automatically appear in different folders without having to manually upload it several times. Conditions: free or not very expensive, the site should not force users to register so that they can see the adopts, english language, no need to reduce files like Toyhouse, a possibility to write text to each adopt, so I can leave a link to each picture (where to buy) also it mustn't delete NSFW content. Do you have any ideas?
