>>24755005. This one is also really annoying when people don't consider it: there needs to be room to draw a dick. If the person's crotch is about to be cut off at the bottom, side, or somehow top of the image, it'll probably be ignored (at least by me). I only put this last because I've seen a lot of edits where editfags will put just the shaft and seem to be fine with it.
TLDR? Here are the things everyone should know before requesting:
1. Editfags need high quality images, with a rule of thumb being that the image should be at least 600x600.
2. The more clothing you request to remove and the baggier the clothes are, the more likely you are to receive a shitty image or no image at all.
3. Editfags have taste too. The more specific or unlikeable a character/fetish is, the less likely you are to receive the image at all.
4. This thread is for screencaps, not fanart. There are some exceptions to this though, read above
5. The image should have ample room for a dick to be added
6. Thank your editfag when they fulfill your request, it makes them feel good ;)
Overall, just try to think in the mind of an editfag: would this be an easy edit? If so, then feel free to post it, and it'll probably be done for you. If not, find another screencap that more accurately fits the requirements above.
And a final word: Sometimes your request will just go ignored even if it is perfect, and you just have to accept that, because this is a free service. If you want guaranteed, high-quality work, please commission an artist.
