I often end up deleting my folders of pics and etc because they are so badly organized, like, I don't like the names I put, the filenames, how messy is to search for something, etc.

I already have gallery-dl, and I want to know where I can download a lot of pictures that interest me, like fan arts, pictures of pretty women (not porn, but the kinda stuff you see in Pinterest) I only know Pinterest and some wallpaper sites), I want to know what sites can I search to find a lot of stuff of any kind. As well as for downloading it.

One of the problems I also have is lack of storage, so I want to recs on this topic as well. Like computers with more storage or SSDs.
