syua:

literally most things that people write off as just ‘textures’ to use in graphics are stolen & unsourced material created by artists or photographers NOT meant to be used as elements in projects without royalty payments. you can say ‘it’s just random tumblr posts they don’t care’ but you wouldn’t want someone to take your work and edit into their work so they can be praised for their beautiful style and creativity even if they just post it on social media w/o profit, would you??

you see it on here a lot especially in (i won’t link anything but i’m sure you know what i mean) those album track ‘aesthetics’ posts, au ‘aesthetic’ posts (you see these less in kpop, but where people use non-royalty free images to kinda craft a visual au), and even just rather typical graphics that have a lot of ‘texture’ elements. and texture packs too!! that’s often where the problem starts; people just collect images (often literal art), compile them in a folder w/o sources, then insist no one can repost those images w/o crediting the person who compiled them. what???

SO may i suggest some places you can get FREE, ROYALTY-FREE elements that are totally legal to use

• creativemarket has 6 free high-quality resources (textures, brushes, fonts, etc), different every week! wow awesome i check it every week
  
• search ‘freebie’ on behance. awesome stuff!!! lots of v nice templates textures and fonts
  
• mockup zone freebies
• unsplash: tons of very nice free photographs, not shitty stock photos
• pexels: same idea. + they have an adobe plugin so you can get photos without closing your editor damn nice
• pixelsquid is a super cool free program (again w a ps plugin that i love) with lottts of super cool hq 3d elements!
• as to not make this too long: spoongraphics, lostandtaken (textures galore), pixeden, freebiesbug.
